[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a transport system, such as Figure 1-5As shown, the transfer system includes: a plurality of weighing and sending tanks 1, each of which is provided with an ash bin 5 on its top; a transfer ash bin 4 arranged on one side of two of the ash bins 5, a first bag dust collector 3 installed on the top of the transfer ash bin 4 for processing powder dust; a vacuum pressure release valve 2 fixed to the transfer ash bin 4; a primary air chute 19 and a secondary air chute 20 arranged at the bottom of the transfer ash bin 4, a telescopic cover being provided at the discharge end of the secondary air chute 20, a transfer terminal being provided at the bottom of the telescopic cover, a lifting motor 18 being provided on the telescopic cover, and a second bag dust collector 14 being provided on the primary air chute 19; and an exhaust assembly arranged on one side of the transfer ash bin 4 for auxiliary dust removal.

[0022] In this embodiment, the weighing and sending tank 1 is used to accurately measure and send powder, and the ash bin 5 arranged on the top is used to store powder, which not only improves the accuracy of transfer, but also ensures the continuous supply of powder. The setting of the transfer ash bin 4 is the core of the transfer system, which plays a role of transfer and buffering. The first bag dust collector 3 can effectively deal with the powder dust generated during the transfer process to ensure the cleanliness of the working environment and the air quality. The internal pressure can be adjusted through the vacuum pressure release valve 2 to ensure the smooth progress of the transfer process. By driving the lifting motor 18, the height of the telescopic cover can be flexibly adjusted, which enhances the flexibility and adaptability of the transfer system. The dust removal effect is further enhanced by the second bag dust collector 14 to ensure that the dust in the transfer process is effectively controlled. The exhaust component can assist the first bag dust collector 3 and the second bag dust collector 14 in dust removal work to further improve the cleanliness of the transfer system.

[0023] In a further preferred embodiment of the utility model, the exhaust assembly includes an air compressor 6, a combined dryer 7 and an air tank 8, the air compressor 6 and the combined dryer 7 are both installed on the wall, the air compressor 6 and the combined dryer 7 are connected, the air tank 8 is arranged on the top of the combined dryer 7 and is connected to the combined dryer 7, a compressed air pipe is installed on the air tank 8, and the compressed air pipe is connected to the first bag dust collector 3 and the second bag dust collector 14.

[0024] In this embodiment, the air compressor 6 and the combined dryer 7 are both installed on the wall. This installation method not only saves space, but also facilitates maintenance and inspection. The main function of the air compressor 6 is to provide an air source for the entire exhaust component. It generates power by compressing air. The main function of the combined dryer 7 is to dry the compressed air generated by the air compressor 6. The dried air can more effectively perform dust removal work, avoiding the problem of reduced dust removal effect caused by excessive air humidity. The main function of the air tank 8 is to store the dried compressed air to ensure that the air source can be provided quickly and stably when needed. This design makes the operation of the entire exhaust component more stable and reduces the impact of air pressure fluctuations on the dust removal effect. When dust removal is needed, the compressed air in the air tank 8 can be quickly transported to the first bag dust collector 3 and the second bag dust collector 14 through the compressed air pipe, providing powerful power for the dust collector, thereby improving the dust removal efficiency.

[0025] In a further preferred embodiment of the utility model, a humidity detector 26 is installed on the compressed air pipe, and the detection probe of the humidity detector 26 extends into the compressed air pipe. A return pipe 27 is installed on the compressed air pipe, and the return pipe 27 is connected to the air compressor 6. The return pipe 27 is provided with a solenoid valve 28.

[0026] In this embodiment, the humidity detector 26 can monitor the humidity of the compressed air in real time and accurately. Once the humidity exceeds the preset range, the humidity detector 26 will immediately send a signal to trigger the corresponding adjustment mechanism. The return pipe 27 is connected to the air compressor 6 to form an air return channel. When the humidity detector 26 detects that the humidity of the compressed air is too high, the solenoid valve 28 will open quickly to allow the compressed air with excessive humidity to flow back to the air compressor 6 through the return pipe 27 for further processing. This design not only prevents air with excessive humidity from entering the dust collector and affecting the dust removal effect, but also ensures a continuous and stable supply of compressed air.

[0027] In a further preferred embodiment of the utility model, multiple weighing and sending tanks 1 are equipped with ash conveying compressed air pipes, multiple compressed air pipes are interconnected, any one of the compressed air pipes is connected to the factory conveying air, multiple weighing and sending tanks 1 are equipped with ash pipes, multiple ash pipes extend into the transfer ash bin 4, the ash conveying compressed air pipes are provided with an exhaust valve 23 and a pneumatic valve 24, multiple ash pipes are provided with a discharge valve 25, and multiple ash conveying compressed air pipes are provided with auxiliary blowing air, discharge air, conveying air and pipeline air replenishment.

[0028] In this embodiment, multiple ash conveying compressed air pipes ensure that each weighing and sending tank 1 can obtain a stable and sufficient supply of compressed air, providing a reliable power source for the transportation of powder. The setting of the ash pipe enables the powder in the weighing and sending tank 1 to be directly and efficiently transported to the transfer ash bin 4, avoiding powder loss and dust problems during the transfer process. The function of the exhaust valve 23 is to discharge the residual gas in the pipeline in time after the transportation is completed to avoid affecting the next transportation, and the pneumatic valve 24 can accurately control the flow and pressure of compressed air as needed to ensure the smooth transportation of powder. The switch of the discharge valve 25 can control the on and off of the ash pipe, thereby realizing precise control of the powder transportation. This design not only improves the flexibility of the transfer system, but also makes the transportation of powder safer and more reliable.

[0029] In a further preferred embodiment of the utility model, a first centrifugal fan 15 and a second centrifugal fan 17 are respectively provided at the bottom of the primary air chute 19 and the secondary air chute 20, a metering and weighing device 13 is provided at the top of the primary air chute 19, a connecting pipe is provided between the metering and weighing device 13 and the transfer ash bin 4, and a pneumatic rotary valve 11 and an electric flow valve 12 are provided on the connecting pipe.

[0030] In this embodiment, the first centrifugal fan 15 and the second centrifugal fan 17 provide power for the powder transportation in the primary air chute 19 and the secondary air chute 20, ensuring that the powder can flow smoothly and efficiently along the chute. The use of the first centrifugal fan 15 and the second centrifugal fan 17 not only improves the transportation efficiency, but also reduces the loss and dust of the powder during the transportation process. The metering and weighing device 13 can accurately measure the amount of powder passing through the chute, providing an important basis for the control and adjustment of the production process. The accuracy and stability of the metering and weighing device 13 are crucial to ensuring the normal operation of the transfer system and the product quality. The pneumatic rotary valve 11 can accurately control the opening and closing of the connecting pipe as needed to ensure that the powder can accurately and timely enter the transfer ash bin 4 after metering and weighing. The electric flow valve 12 can adjust the flow of the powder to meet different production needs.

[0031] In a further preferred embodiment of the utility model, a rotating cantilever is provided at the bottom of the secondary air chute 20, a rotating drive motor 16 is provided at the bottom of the rotating cantilever, and the rotating drive motor 16 is installed on the ground, and any two of the ash pipes are provided with a clearing and maintenance valve, and any two of the ash pipes are provided with multiple pressure devices.

[0032] In this embodiment, the angle of the rotary cantilever is changed by the drive of the rotary drive motor 16, and the angle and direction of the secondary air chute 20 are changed to adapt to different transportation requirements. This flexibility improves the transportation efficiency.

[0033] In a further preferred embodiment of the utility model, a Roots blower 9 is provided on one side of the metering and weighing device 13 , an exhaust end of the Roots blower 9 extends to the metering and weighing device 13 , and an electric heater 10 is provided on the exhaust pipe of the Roots blower 9 .

[0034] In this embodiment, the setting of the Roots blower 9 can effectively provide a stable airflow for the metering and weighing device 13. This airflow not only helps to reduce the dust and dispersion of the powder during the metering process, but also ensures the uniform distribution of the powder in the metering and weighing device 13, thereby improving the accuracy of the metering. Through the heating effect of the electric heater 10, the airflow discharged by the Roots blower 9 can be heated to a suitable temperature. This measure is particularly important in cold environments. It can prevent the powder from agglomerating or reducing its fluidity due to low temperature, thereby ensuring the normal operation of the metering and weighing device 13 and the accuracy of the metering.

[0035] In summary, compared with the relevant technology, the present device can transfer and buffer the powder in transportation by setting up the transfer ash bin 4, and can perform more precise weighing of the transported powder by setting up the weighing and sending tank 1 and the metering weighing device 13 to increase the accuracy of powder transportation, and can process the dust generated by powder discharge by setting up the air compressor 6, the combined dryer 7, the air storage tank 8, the first bag dust collector 3 and the second bag dust collector 14 to reduce air pollution.

[0036] The working principle of the operation system provided by the utility model is as follows:

[0037] The powder in the ash bin 5 is sent to the transfer ash bin 4 through the ash pipe by the weighing and sending tank 1. The weighing and sending tank 1 is equipped with a weighing device to realize data collection of the conveying volume. In order to ensure the reliability and stability of the conveying, auxiliary air and pipeline air supply are configured to improve the reliability. When abnormal working conditions occur and cause pipe blockage, the position of the pipe blockage is judged by the pressure gauge, and the blockage is cleared according to the position of the pipe blockage. When the front end is blocked, all valves are closed, and the front end clearing valve is opened to release the pressure in the pipeline to loosen the blocked pipe. When the pressure in the pipeline is released, the front end clearing valve is closed and the auxiliary air is turned on. When the pressure of the pressure gauge continues to reach the pipe blocking pressure, the auxiliary air is closed and the front end clearing valve is opened to loosen the powder blocked by the pipe. This is repeated until the pressure of the pressure gauge continues to drop after the auxiliary air is turned on. When pressure appears in the other pressure gauge, it means that the surface clearing is successful and the pipe is switched to the conveying mode. When the rear end is blocked, the front end valve is closed, the auxiliary air is turned on, the end clearing inspection valve is closed, and the end clearing valve is opened. The end is cleared of blocked air, and the discharge port is rotated by the rotary drive motor 16. When the discharge port is aligned with the transfer terminal, the telescopic cover is released by the lifting motor 18, and the first bag dust collector 3, the second bag dust collector 14, the first centrifugal fan 15, the second centrifugal fan 17, the Roots blower 9, the electric heater 10, the metering and weighing device 13, the electric flow valve 12, and the pneumatic rotary valve 11 are turned on to start discharging and loading to the transfer terminal. The powder passes through the pneumatic rotary valve 11, the electric flow valve 12, the metering and weighing device 13, the primary air chute 19, the buffer tank 21, the rotary joint 22, the secondary air chute 20, and the telescopic cover to flow into the transfer terminal. The dust generated during this period is collected by the first bag dust collector 3 and the second bag dust collector 14 through the telescopic cover and the secondary air chute 20. The collected dust flows into the secondary air chute 20 through the primary air chute 19, the buffer tank 21, and the rotary joint 22, and then flows into the transfer terminal such as the cargo ship.
