Description

Technical Field

[0001] The utility model belongs to the field of negative pressure feeding, and in particular relates to an air locking device for negative pressure feeding. Background Art

[0002] Negative pressure suction is a common material conveying method, primarily suitable for conveying powdered, granular, and fibrous materials. Its operating principle is to draw material into the conveying system through negative pressure, where it undergoes compression, conveying, and discharge during the conveying process. Specifically, a negative pressure suction system typically consists of a suction port, suction pipe, fan, and filter silo. When the fan is activated, the suction port experiences low pressure, drawing material into the suction pipe. The fan then propels the material downstream through the pipe, while the high air velocity in the pipe also compresses the material. After reaching its destination, the material is discharged through a discharge door. The air lock device, a special type of star-shaped dust discharge valve, shuts off the fan and locks in air, providing a more secure seal and preventing air from being drawn in or out of the discharge port. It is suitable for handling fine particles and powdery materials, ensuring uniform material discharge and operating under negative pressure. It can also serve as an environmentally friendly dust removal silo discharge device. However, when using existing air lock devices, there is still a gap between the internal separating wheel's separating blades and the valve body, resulting in a poor air lock effect. Furthermore, when disassembling and maintaining the air lock device, the separating wheel must be removed as horizontally as possible to prevent damage caused by contact between the separating wheel blades and the interior of the valve body. This operation results in poor positioning during disassembly and installation of the air lock device. Utility Model Content

[0003] The purpose of the utility model is to provide a negative pressure feeding air locking device, which has the advantages of increasing the sealing and air locking effect of the air locking device, increasing the carrying and conveying effect of the partition plate on the material, increasing the use efficiency, and improving the positioning effect of the device during installation and disassembly, thereby bringing protection to the operation.

[0004] The above technical purpose of the present utility model is achieved through the following technical solutions: a negative pressure feeding and air locking device, comprising a shell, the interior of the shell is rotatably connected to a rotating rod through a bearing, the top of the shell is connected to a feed port, the bottom of the shell is connected to a discharge port, a partition plate is fixedly installed on the surface of the rotating rod, one end of the partition plate is fixedly adhered to a silicone strip, a flange is fixedly sleeved on the surface of one end of the shell, a mounting plate is provided on one side of the flange, a fixed block two is fixedly installed on one side of the mounting plate, a fixed block one is fixedly installed on both sides of the shell and is located on one side of the fixed block two, and a guide rod is fixedly installed on one side of the fixed block two and passes through one end of the fixed block one.

[0005] The above technical solution is adopted: when the negative pressure feeding air locking device is used, the mounting plate is respectively installed and fastened with the feed port and the discharge port and the external material passage, and the mounting hole is installed with the mounting plate. During the operation of the rotating motor, the rotating rod will be driven to rotate, and the rotating rod will drive the partition plate to realize the movement trend around the rotating rod as the center of the circle. The partition plate has a clockwise running trend, and the material will be carried through the arc groove, and the contact between the silicone strip and the inside of the shell will cooperate to achieve the sealing and air locking effect on the inside of the shell. This setting can effectively increase the sealing and air locking effect of the air locking device, and increase the carrying and conveying effect of the partition plate on the material, thereby increasing the use efficiency.

As the second fixing block gradually moves away from the first fixing block, the guide rods ensure horizontal movement of the mounting plate, allowing the divider plate to achieve stable lateral movement within the housing, reducing the difficulty in removing the divider plate due to skewed movement within the housing. Once the guide rods are released from the guide holes, the mounting plate and divider plate are removed. During subsequent installation of the mounting plate and divider plate, the mounting plate takes precedence. This arrangement improves the positioning accuracy of the device during installation and removal, ensuring operational reliability.

[0006] The present invention is further configured such that the number of the partition plates is multiple and they are evenly distributed on the surface of the rotating rod at equal distances.

[0007] By adopting the above technical solution, the materials inside the shell can be evenly transported through the partition plate.

[0008] The present invention is further configured such that an arc-shaped groove is formed on one side of the partition plate, and the silicone strip is in contact with the inner side of the shell.

[0009] The above technical solution is adopted: the material is supported by the arc groove in combination with the partition plate, and the contact between the silicone strip and the inside of the shell will cooperate to achieve the sealing and wind locking effect on the inside of the shell.

[0010] The present invention is further configured such that one end of the feed port and the discharge port are both fixedly sleeved with a mounting plate, and a mounting hole is provided inside the mounting plate.

[0011] The above technical solution is adopted: the mounting plate is respectively matched with the feed port and the discharge port and the external material passage pipe for installation and fastening, and the mounting hole is matched with the mounting plate for installation.

[0012] The present invention is further configured such that a guide hole for the guide rod to pass through is provided inside the fixing block 1, and the guide hole and the guide rod are slidably connected to each other.

[0013] The above technical solution is adopted: the movement of the second fixed block is guided by the sliding connection between the guide hole and the guide rod.

[0014] The present invention is further configured such that a rotary motor is provided on one side of the mounting plate, and an output end of the rotary motor is fixedly sleeved with a rotary rod via a coupling.

[0015] Adopting the above technical solution: the operation of the rotating motor will drive the rotating rod to rotate.

[0016] The present invention is further configured such that a fixing ring fixedly connected to the mounting plate is fixedly sleeved on the surface of the rotating motor.

[0017] The above technical solution is adopted: the support and fixation are carried out by cooperating with the rotating motor through the fixing ring.

[0018] The present invention is further configured such that a bolt penetrating the mounting plate to the inner side of the flange is provided on one side of the mounting plate, and threaded holes for threaded connection with the bolt are provided inside the mounting plate and the flange.

[0019] By adopting the above technical solution, the mounting plate and the flange are fastened together by means of threaded connection between the bolts and the threaded holes.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. When using the negative pressure feeding air lock device of this utility model, the operation of the rotary motor will drive the rotating rod to rotate, and the rotating rod will drive the partition plate to realize the movement trend around the rotating rod as the center. The partition plate will move clockwise, and will realize the support of the material through the arc groove. The contact between the silicone strip and the interior of the shell will cooperate to achieve the sealing and air locking effect inside the shell. This setting can effectively enhance the sealing and air locking effect of the air lock device, and increase the carrying and conveying effect of the partition plate on the material, thereby increasing the use efficiency.

[0022] 2. In the use of the negative pressure feeding and air locking device of the utility model, when the partition plate needs to be maintained and replaced, the mounting plate and the flange can be removed first by removing the bolts, and then the mounting plate and the fixed block 2 can be moved laterally by setting the guide rod and the guide hole. As the fixed block 2 gradually moves away from the fixed block 1, the guide rod ensures the horizontal movement of the mounting plate, so that the partition plate can achieve stable lateral movement inside the shell, reducing the inconvenience of removing the partition plate inside the shell due to skewed movement. Then, when the guide rod is out of the guide hole, the mounting plate and the partition plate are disassembled. In the subsequent installation of the mounting plate and the partition plate, the mounting plate is given priority. This setting can improve the positioning effect of the device during installation and disassembly, and bring protection to the operation. BRIEF DESCRIPTION OF THE DRAWINGS
