Description

Technical Field

[0001] This application relates to the field of calcium carbonate powder production technology, and in particular to an automatic air pressure regulating device for pneumatic conveying. Background Technology

[0002] Calcium carbonate is made primarily from limestone, which undergoes mechanical crushing, grinding, and other processes to form dry or wet powder, followed by grading to create products with different particle sizes. It is suitable for numerous industries including papermaking, plastics, rubber, inks, chemical building materials, sealing materials, daily chemicals, food, and pharmaceuticals.

[0003] Currently, the production of calcium carbonate typically employs a combination of large-scale dry grinding equipment, such as vertical mills or ball mills, and multi-stage ultrafine classifiers. First, limestone transported from the quarry is coarsely crushed using a crusher, then pulverized into fine limestone powder using grinding machinery. Finally, the powder is graded using screening machinery. Powder meeting the particle size requirements is packaged and stored as product; otherwise, it is returned to the grinding mill for further grinding.

[0004] In the production of calcium carbonate, a gas supply is required to ensure the normal reaction of calcium carbonate within the processing equipment. To ensure a stable gas supply, the air pressure needs to be regulated. However, current gas supply equipment struggles to automatically adjust the air pressure when it fluctuates. This fluctuation negatively impacts the stability of the gas supply to the processing equipment, affecting the quality of the calcium carbonate, and thus requires improvement. Utility Model Content

[0005] To improve the stability of the gas supply pressure, this application provides an automatic pressure regulating device for pneumatic conveying.

[0006] The automatic air pressure regulating device for pneumatic conveying provided in this application adopts the following technical solution: An automatic air pressure regulating device for pneumatic conveying includes a housing and an regulating mechanism. An air outlet pipe is fixedly installed on the left side of the housing, and an industrial control computer is fixedly installed on the front of the housing. The regulating mechanism is located on the right side of the housing and includes an air inlet pipe installed on the right side of the housing. An exhaust fan is fixedly installed on the inner wall of the air inlet pipe. A partition is fixedly installed on the inner wall of the housing. Two sets of openings are provided on the right side of the partition. Two support rods are fixedly installed on the left side of the partition. A baffle is rotatably connected to the outer surface of each support rod. A control rod is fixedly installed on the left side of each baffle. A control rod is fixedly installed on the left side of the housing. A U-shaped plate has a threaded rod rotatably connected to its inner wall via a bearing. A servo motor is fixedly installed on the inner top wall of the housing. The output end of the servo motor is fixedly installed to the top end of the threaded rod. A set of perforated control plates is threadedly connected to the outer surface of the threaded rod. Two sets of adjusting plates are fixedly installed on the upper surface of the perforated control plates. Each adjusting plate has an adjusting groove on its upper surface. A T-shaped block is slidably connected to the inner wall of each adjusting groove. A control ring is rotatably connected to the outer surface of each control rod. The outer surfaces of the two sets of control rings are fixedly installed to the bottom surfaces of the two sets of T-shaped blocks. A wind pressure sensor is fixedly installed on the inner wall of the housing.

[0007] By adopting the above technical solution, a wind pressure sensor can be installed to sense the wind pressure inside the casing. When the wind pressure changes, the wind pressure sensor immediately sends a signal to the industrial control computer. The industrial control computer precisely controls the forward and reverse rotation of the servo motor according to the wind pressure, so that the threaded rod can control the up and down movement of the perforated adjustment plate. With the cooperation of the control rod, T-block and control ring, the baffle moves up and down, realizing real-time adjustment of wind pressure, ensuring wind pressure stability and ensuring normal production of calcium carbonate.

[0008] Optionally, the left side of the partition is provided with two sets of blocks, and the right side of the two sets of blocks is fixedly installed to the left end of the two sets of support rods respectively.

[0009] By adopting the above technical solution, the stop block limits the baffle and prevents the baffle from slipping.

[0010] Optionally, two fixing plates are fixedly installed on the right side of the partition, and the sides of the two fixing plates that are far apart from each other are fixedly installed to the inner top wall and the inner bottom wall of the housing, respectively.

[0011] By adopting the above technical solution, the fixing plate can reinforce the casing and prevent the partition from loosening during use.

[0012] Optionally, two mounting plates are fixedly installed on the front of the housing, and the two sets of mounting plates are fixedly installed on the front and back sides of the housing respectively, with their sides close to each other.

[0013] Optionally, a dustproof net is fixedly installed on the inner wall of the air inlet duct, and the dustproof net is located on the right side of the exhaust fan.

[0014] By adopting the above technical solution, the dustproof net can block dust and prevent it from entering the device.

[0015] Optionally, a display is fixedly mounted on the front of the housing, and the display is located on the left side of the industrial computer.

[0016] By adopting the above technical solution, the wind pressure is displayed on a display panel, which makes it easier for staff to control the device.

[0017] Optionally, a fixing ring is fixedly installed on the outer surface of the air inlet pipe, and the left side of the fixing ring is fixedly installed on the right side of the housing.

[0018] By adopting the above technical solution, the fixing ring is used to reinforce the air inlet pipe and prevent it from becoming loose.

[0019] Optionally, the wind pressure sensor is located between the air outlet duct and the partition.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating a wind pressure sensor, the internal wind pressure of the machine casing can be sensed. When a change in wind pressure occurs, the wind pressure sensor immediately sends a signal to the industrial control computer. Based on the wind pressure, the industrial control computer precisely controls the forward and reverse rotation of the servo motor, enabling the threaded rod to control the up and down movement of the perforated adjustment plate. With the cooperation of the control rod, T-block, and control ring, the baffle moves up and down, achieving real-time adjustment of wind pressure, ensuring stable wind pressure, and ensuring normal production of calcium carbonate. 2. When the wind pressure changes, the servo motor 206 is activated. The servo motor 206 drives the threaded rod 209 to rotate, and the perforated control plate 215 moves up and down, causing the adjusting plate 210 to move up and down. The adjusting plate 210 drives the T-block 214 to move up and down, causing the control ring 213 to drive the control rod 212 to move, causing the baffle 208 to rotate around the support rod 216 as the center, controlling the opening and closing of the control port 204, thereby completing the adjustment of the wind pressure.

[0034] The implementation principle of the pneumatic conveying air pressure automatic adjustment device in this application embodiment is as follows: During use, the exhaust fan 207 is activated to draw air and blow it into the interior of the housing 1, allowing the air to enter the inlet 204. The air pressure sensor 202 senses the air pressure inside the housing 1, and upon a change in air pressure, the air pressure sensor 202 sends a signal to the industrial control computer 102. The industrial control computer 102 then activates the servo motor 206, which drives the threaded rod 209 to rotate. As the threaded rod 209 rotates, the threaded rod 209... 09 can be moved up and down by the perforated control plate 215, which in turn moves the adjustment plate 210 up and down. As the adjustment plate 210 moves, it can drive the T-block 214, which in turn moves the T-block 214 up and down. This causes the control ring 213 to drive the control rod 212, which in turn drives the baffle 208 to rotate around the support rod 216, causing the baffle 208 to open and close the opening 204, thereby completing the adjustment of the wind pressure.
