[0002] In industrial production, ton-sized bags of PVC powder need to be transported to processing equipment via an air separation system before further processing. The entire transportation process involves bag unpacking, unloading, unloading, and air conveying. During unloading, operators are required to monitor the unloading process in real time, adjusting the fan on and off and the amount of unloading. This high workload and the instability of the operators lead to a lack of stability in the entire conveying system. Large amounts of dust can overflow from receiving devices such as silos, causing them to float. This creates a high level of dust on site, resulting in a poor working environment and seriously affecting the health of the operators. Utility Model Content
[0003] In response to the above technical problems, the utility model provides a ton bag PVC powder conveying system, which is used to solve the problems of low conveying efficiency and poor stability caused by the need for manual monitoring and control of the opening and closing of the fan and the amount of discharge when the ton bag PVC powder is discharged.

The other end of the air-transmitted rotary feeding valve is connected to a processing silo. The signal control end of the remote air pressure gauge is respectively connected to the signal control end of the Roots blower and the electric gate valve.
[0006] Furthermore, the unloading device includes a discharge bin and a buffer hopper. The top of the discharge bin is provided with a pouring port and a dust suction port. The dust suction port is connected to a dust suction device. The bottom of the discharge bin is connected to the buffer hopper port.
[0007] Furthermore, the dust collection device includes a cyclone dust separator and a cyclone rotary discharge valve. A dust removal fan is installed on the cyclone dust separator. The exhaust port of the cyclone dust separator is connected to the dust collection port of the silo and the hopper port of the buffer hopper. The bottom of the cyclone dust separator is connected to the buffer hopper through the cyclone rotary discharge valve.
[0008] Furthermore, an exhaust chamber is installed on the material pipe between the electric gate valve and the air-transported rotary discharge valve, and the exhaust chamber is connected to the exhaust port of the cyclone dust separator.
[0009] Furthermore, an air cooler is installed between the Roots blower and the remote wind pressure gauge.
[0010] Furthermore, a filter is installed between the remote air pressure gauge and the air-transmitting rotary discharge valve.
[0011] Furthermore, there are two discharge bins.
[0012] Compared with the prior art, the beneficial effect of the present invention is that the present invention interlocks the signal control end of the remote air pressure gauge with the signal control end of the Roots blower and the electric gate valve respectively.

[0016] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.
[0017] A ton bag PVC powder conveying system includes a discharge device, an air-transmitted rotary discharge valve 5, and a remote air pressure gauge 3. The discharge port of the discharge device is connected to the air-transmitted rotary discharge valve 5 via a material pipe, and an electric gate valve 7 is installed on the material pipe. One end of the air-transmitted rotary discharge valve 5 is connected to a Roots blower 1 via a remote air pressure gauge 3, and the other end of the air-transmitted rotary discharge valve 5 is connected to a processing silo 14. The signal control end of the remote air pressure gauge 3 is respectively connected to the signal control ends of the Roots blower 1 and the electric gate valve 7. The utility model interlocks the signal control end of the remote air pressure gauge 3 with the signal control ends of the Roots blower 1 and the electric gate valve 7. The remote air pressure gauge 3 controls and adjusts the opening of the gate valve according to the air pressure of the Roots blower 1, thereby controlling the amount of material discharged, achieving interlocking operation between equipment and ensuring stable operation of the conveying system.
[0018] The unloading device includes a discharge bin 9 and a buffer hopper 8. A discharge port 16 and a dust suction port 15 are provided on the top of the discharge bin 9. The powder is discharged into the hopper along the discharge port 16 through a lifting device such as an electric hoist, and then flows to the buffer hopper 8. The buffer hopper 8 receives the poured PVC powder and serves as a temporary storage for the powder. The dust suction port 15 is connected to a dust suction device to collect the powder that overflows and floats during the unloading process to prevent it from escaping and affecting the working environment.
[0019] The dust collection device includes a cyclone dust separator 12 and a cyclone rotary discharge valve 11. A dust removal fan 13 is installed on the cyclone dust separator 12. The dust removal fan 13 is located at the top of the cyclone separator, forming a negative pressure on the cyclone separator, forming negative pressure dust removal on the discharge bin 9, and suppressing dust overflow. The exhaust port of the cyclone dust separator 12 is connected to the dust suction port 15 of the bin and the bucket mouth of the buffer hopper 8. The bottom of the cyclone dust separator 12 is connected to the buffer hopper 8 through the cyclone rotary discharge valve 11. The formed PVC dust is transported to the buffer hopper 8 through the cyclone rotary discharge valve 11 for secondary recycling.
[0020] An exhaust chamber 6 is installed on the material pipe between the electric gate valve 7 and the air-conveyed rotary discharge valve 5. The exhaust chamber 6 is connected to the exhaust port of the cyclone dust separator 12, forming a slight negative pressure in the exhaust chamber 6 to avoid the powder bridging phenomenon here.
[0021] An air cooler 2 is installed between the Roots blower 1 and the remote air pressure gauge 3 to cool the high-temperature and high-pressure air compressed by the Roots blower 1.
[0022] A filter 4 is installed between the remote wind pressure gauge 3 and the air-transmitting rotary discharge valve 5 to filter impurities in the air to avoid affecting the quality of the PVC powder.
[0023] The two discharge bins 9 are provided to discharge materials together, thereby improving the discharge efficiency.
[0024] When using:
[0025] First, start the Roots blower 1 and the cyclone dust separator 12, then use the electric hoist to lift the PVC ton bag, and then pour the PVC powder into the two discharge silos 9 through the discharge port 16. After the material is retained in the buffer silo, it passes through the electric gate valve 7 and falls into the exhaust chamber 6. Under the action of gravity, it falls to the air-supplied rotary discharge valve 5. The air heated and pressurized by the Roots blower 1 is transported to the air cooler 2 to cool the high-temperature air, and then transported to the filter 4 to remove impurities and filter the air. The filtered high-pressure air transports the PVC powder transported by the air-supplied rotary discharge valve 5 to the processing silo 14 for further processing.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
