Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a five-station material pneumatic mutual transmission system. Background Art

[0002] Pneumatic conveying systems are often used to address environmental issues during the transportation of powdered materials or other materials. They can significantly improve the working environment and greatly reduce labor intensity, making them widely used in industries such as industry and agriculture. Pneumatic conveying systems have a simple structure and are easy to operate, and can be used for horizontal, vertical, or inclined conveying.

[0003] Pneumatic conveying can be roughly divided into two types based on its working principle: suction and pressure. The suction type is suitable for centralized conveying from multiple locations to one, that is, there are multiple feeding points and a single unloading point. The pressure type is suitable for decentralized conveying from one location to multiple locations, that is, there is one feeding point and multiple unloading points. However, in some specific scenarios, it is necessary to solve the problem of point-to-point conveying. The initial idea was to use a mechanical material conveyor line. However, its procurement cost is high, the floor space is very large, and the transmission speed is slow, which cannot meet the requirements of the production cycle. In addition, some workstations require two-way material transfer, which requires the modification of the standard one-way mechanical conveyor line, which is bound to further increase the purchase cost and floor space of the mechanical conveyor line. Therefore, technical personnel are urgently needed to solve the above problems. Utility Model Content

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and, after continuous experimentation and modification by technicians with many years of R&D experience in this industry, ultimately led to the emergence of the five-station material pneumatic transfer system.

[0005] In order to solve the above-mentioned technical problems, the present invention relates to a five-station material pneumatic mutual transfer system, in which materials are transferred and exchanged between stations using the energy of air flow. The five-station material pneumatic mutual transfer system includes station one, station two, station three, station four, station five, an air supply main line, an air supply branch line one, an air supply branch line two, an air supply branch line three, an air supply branch line four, an air supply branch line five, a connecting transition line, a one-inlet three-outlet reversing valve one, a one-inlet three-outlet reversing valve two, and a pressure gas supply unit. The pressure gas supply unit is used to match the air supply main line to supply it with positive pressure air or negative pressure air. The inlet end of the one-inlet three-outlet reversing valve one is connected to the air supply main line, and its three parallel outlet ends are respectively connected to the inlet end of station one, station two, and the one-inlet three-outlet reversing valve two by means of the air supply branch line one, the air supply branch line two, and the connecting transition line. The three parallel outlet ports of the one-inlet-three-outlet reversing valve 2 are connected to the third, fourth and fifth stations in a one-to-one correspondence via the third, fourth and fifth gas supply branch lines respectively.

[0006] As a further improvement to the technical solution disclosed in this utility model, the pressurized gas supply unit includes an industrial vortex high-pressure air pump and an air direction switch. An air inlet and an air outlet are located at the top of the industrial vortex high-pressure air pump. An exhaust port is located at the top of the air direction switch, and three parallel air inlets, air inlet 1, air inlet 2, and air inlet 3, are located at the bottom. The exhaust port is connected to the main air supply line. Air inlet 1 and air inlet 2 are connected to the air inlet and air outlet, respectively, in a one-to-one correspondence, while air inlet 3 is connected to the atmosphere.

[0007] As a further improvement to the technical solution disclosed in this utility model, the pressurized gas supply unit also includes an anemometer, a transmitter, and a frequency converter. The anemometer is paired with the main gas supply line to measure the gas flow rate within the main gas supply line. The transmitter converts the flow rate measured by the anemometer into an electrical signal. With the intervention of the frequency converter, the operating power of the industrial vortex high-pressure air pump can be adaptively adjusted.

[0008] As a further improvement to the technical solution disclosed in this utility model, the five-station pneumatic material transfer system also includes a first check valve, a second check valve, and a bypass pipe. The first and second check valves are assembled in series on the main air supply line. The bypass pipe's ends are connected to the first and second check valves, respectively.

[0009] As a further improvement of the technical solution disclosed in the utility model, the main gas supply line, gas supply branch line one, gas supply branch line two, gas supply branch line three, gas supply branch line four, gas supply branch line five and the connecting transition line are all made of transparent materials.

[0010] As a further improvement of the technical solution disclosed in the utility model, the five-station pneumatic material transfer system also includes a temporary storage capsule. When the material to be transferred is powdered material, it is quantitatively loaded into the temporary storage capsule.

[0011] As a further improvement to the technical solution disclosed in this utility model, the corners of air supply branch lines 1, 2, 3, 4, and 5 are all formed with arc transitions. Assuming the length of the temporary storage capsule is L, the diameter D is ≤ 1 / 2L, and the radius of the arc transition corner is r, then r ≥ 2.5L.

[0012] In practical applications, the five-station pneumatic material transfer system disclosed in this utility model can achieve the following beneficial technical effects, specifically:

[0013] 1) Abandoning the traditional mechanical material conveying line design concept, in this utility model, the pressure gas supply unit has the function of supplying positive pressure air and negative pressure air, and switches according to the actual material conveying needs. At the same time, the reversing valve performs the gas flow direction switching operation, and the material can be freely transferred and transposed between the five stations with the help of the air flow energy. The conveying process is smooth, the conveying speed is fast, and the purchase and maintenance costs are low. During use, it is only necessary to regularly clean the main air supply line, the air supply branch line and the connecting transition line to keep their inner walls clean;

[0014] 2) Compared to traditional mechanical material conveying lines, the five-station pneumatic material transfer system has a very simple design structure, which is easy to implement and requires less space, making it easier to arrange in the workshop. While maintaining the same energy consumption, pneumatic conveying can achieve longer distances or transport larger quantities and heavier materials.

[0015] 3) According to the specific needs of downstream manufacturers, the five-station pneumatic material transfer system can be easily and quickly modified to make it suitable for the transfer of solid, powder or granular materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the present invention in conjunction with specific embodiments. Figure 1The schematic diagram of the structure of the five-station material pneumatic mutual transmission system disclosed in the present invention is shown. It can be seen that it is mainly composed of station 1, station 2, station 3, station 4, station 5, gas supply main line 6, gas supply branch line 1, gas supply branch line 2, 8, gas supply branch line 3, gas supply branch line 4, 10, gas supply branch line 5, 11, connecting transition line 12, one-inlet and three-outlet reversing valve 1, one-inlet and three-outlet reversing valve 2, 14 and pressure gas supply unit 15. Among them, the pressure gas supply unit 15 is mainly composed of an industrial vortex high-pressure air pump 151 and a wind direction switch 152 (such as Figure 4 As shown in the figure, it is used to match the main air supply line 6 to supply positive pressure air or negative pressure air to it. The inlet of the one-inlet three-outlet reversing valve 13 is connected to the main air supply line 6, and its three parallel outlets are connected to the inlet of station 1, station 2, and one-inlet three-outlet reversing valve 2 14 respectively by means of the air supply branch line 1 7, the air supply branch line 2 8, and the connecting transition line 12 (as shown in the figure). Figure 2 The three parallel outlet ports of the one-inlet-three-outlet reversing valve 2 14 are connected to the station 3 3, the station 4 4, and the station 5 5 in a one-to-one correspondence via the gas supply branch line 3 9, the gas supply branch line 4 10, and the gas supply branch line 5 11 (as shown in FIG. Figure 3 ).

[0027] In the present invention, the traditional mechanical material conveying line design concept is abandoned. Under the coordinated action of the industrial vortex high-pressure air pump 151 and the wind direction switcher 152, the pressure gas supply unit 15 has the function of supplying positive pressure air and negative pressure air, and switches according to the actual material conveying needs. At the same time, the reversing valve (including one-inlet and three-outlet reversing valve one 13 and one-inlet and three-outlet reversing valve two 14) performs the gas flow direction switching operation, and the material can be freely transferred and replaced between five stations (including station one 1, station two 2, station three 3, station four 4 and station five 5) with the help of air flow energy. The conveying process is smooth, the conveying speed is fast, and the purchase and maintenance costs are low. During use, it is only necessary to regularly clean the main air supply line 6, the air supply branch line (including air supply branch line one 7, air supply branch line two 8, air supply branch line three 9, air supply branch line four 10 and air supply branch line five 11) and the connecting transition line 12 to keep the inner wall clean.

[0028] Depend on Figure 1 As shown in the , it is also clear that compared to traditional mechanical material conveying lines, the five-station pneumatic material transfer system disclosed in this utility model has a very simple design structure, which is easy to implement and requires less space, making it easier to arrange it in a workshop. While maintaining the same energy consumption, pneumatic conveying can achieve longer distances or transport larger quantities and heavier materials.

[0029] It should also be noted that, depending on the specific needs of downstream manufacturers, the five-station pneumatic material transfer system can be easily and quickly redesigned and modified to make it suitable for the transfer of solid, powder or granular materials.

[0030] like Figure 4 As shown in FIG, the top of the industrial vortex high-pressure air pump 151 is provided with an air inlet and an air outlet. Figure 5 、 6 As shown in Figures 7 and 8, an exhaust port 1521 is provided at the top of the wind direction switcher 152, and three parallel air inlets 1 1522, 1523, and 1524 are provided at the bottom. The exhaust port 1521 is connected to the main air supply line 6. The air inlet 1 1522 and the air inlet 2 1523 are respectively connected to the air inlet and air outlet opened on the top of the industrial vortex high-pressure air pump 151, while the air inlet 3 1524 is connected to the atmosphere. In actual application, when the pressure gas supply unit 15 needs to switch between supplying positive pressure air and supplying negative pressure air, the gear transmission mechanism in the wind direction switcher 152 is activated, and the exhaust port 1521 switches from being connected to the air inlet 1 1522 to being connected to the air inlet 2 1523, or from being connected to the air inlet 2 1523 to being connected to the air inlet 1 1522. When compressed air is temporarily not needed in the air supply main line 6, the exhaust port 1521 is connected to the air inlet 1524, and the compressed gas generated by the industrial vortex high-pressure air pump 151 is directly discharged into the external atmospheric environment.

[0031] Under the premise of ensuring that the five-station material pneumatic mutual transmission system can stably and quickly transmit materials, in order to reduce the energy consumption of the pressure gas supply unit 15 as much as possible and to make the industrial vortex high-pressure air pump 151 have a longer service life, as a further optimization of the technical solution disclosed in the utility model, Figure 4 As shown in , the pressure gas supply unit 15 is further provided with an anemometer 153, a transmitter 154 and a frequency converter 155. The anemometer 153 is matched with the main gas supply line 6 to measure the gas flow rate in the main gas supply line 6. The transmitter 154 is used to convert the physical quantity of the flow rate measured by the anemometer 153 into an electrical signal, and under the intervention of the frequency converter 155, the operating power of the industrial vortex high-pressure air pump 151 can be adaptively adjusted. In this way, during the operation of the five-station material pneumatic mutual transmission system, the industrial vortex high-pressure air pump 151 can adjust its operating power according to actual conditions.

[0032] Furthermore, by Figure 1As shown in the figure, it can be clearly seen that the five-station material pneumatic mutual transmission system is also equipped with a check valve 16, a check valve 2 17 and a bypass pipe 18. The check valve 16 and the check valve 2 17 are assembled in series on the main air supply line 6. The two ends of the bypass pipe 18 are connected to the check valve 16 and the check valve 2 17 respectively. In this way, when the main air supply line 6 is filled with negative pressure air, the material performs a reverse displacement movement under the action of the negative pressure effect. At the same time, the air flow flowing through the one-inlet and three-outlet reversing valve 13 bypasses the bypass pipe 18 and enters the industrial vortex high-pressure air pump 151, and the material is stopped at a specific position of the main air supply line 6 (aligned with the bypass pipe 18). When the main air supply line 6 is filled with positive pressure gas, the bypass pipe 18 is in a blocked state, and the material performs a positive displacement movement under the action of the pressure effect.

[0033] As a further optimization of the above technical solution, the main air supply line 6, branch air supply line 1 7, branch air supply line 2 8, branch air supply line 3 9, branch air supply line 4 10, branch air supply line 5 11, and connecting transition line 12 are all made of transparent materials. This allows workers to monitor the specific status and location of materials in real time during the actual operation of the five-station pneumatic material transfer system, and to intervene immediately if any jams or blockages occur.

[0034] After a period of trial operation, we discovered the following thorny issue: powdered materials tend to adhere to the sidewalls of the pipes, increasing air resistance and making cleaning difficult, especially in high humidity. In light of this, our company has developed a technical solution that utilizes temporary storage capsules 19 to transport powdered materials. When the powdered material is transported, it is quantitatively loaded into temporary storage capsules 19. Upon arrival at the designated workstation, workers open the capsules 19 and remove the material.

[0035] like Figure 1 、 8 As shown in FIG, the corners of air supply branch lines 1 7, 2 8, 3 9, 4 10, and 5 11 are all formed with arc transitions. Assuming the length of temporary storage capsule 19 is L, the diameter D is ≤ 1 / 2L, and the radius of the arc transition corner is r, then r ≥ 2.5L. This effectively prevents the inner walls of the corners of air supply branch lines 1 7, 2 8, 3 9, 4 10, and 5 11 from being severely scratched due to long-term friction, as well as damage from rigid collision forces.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
