Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluidization device technology, specifically a pump chamber fluidization device. Background Technology
[0002] Powder fluidization refers to a dynamic state of solid particles in a fluid. When a fluid passes through a layer of solid particles, if the flow velocity reaches a certain value, the solid particles will exhibit flow characteristics similar to a fluid. This phenomenon is called fluidization.
[0003] The existing Chinese utility model patent with publication number CN217147785U discloses a powder fluidization device, including a fluidization hopper for carrying powder and having a receiving cavity, an air extraction pipe connected to the receiving cavity, and a fluidization component disposed within the fluidization hopper to fluidize the powder. The fluidization component includes two opposing comb teeth. The fluidization hopper has at least two opposing first sidewalls, and each of the two opposing first sidewalls has an air inlet, which is opposite to the other sidewall. The air inlets are located in the area where the comb teeth are projected onto the first sidewall. Through the cooperation of the air inlets and the comb teeth, the opposing air inlets can form a reflux airflow, causing the powder falling into the receiving cavity of the fluidization hopper to flow in the reflux airflow, forming a powder fluidization phenomenon. This facilitates the extraction of powder by the air extraction pipe and effectively reduces the occurrence of powder accumulating at the bottom of the fluidization hopper and clogging the air extraction pipe. The arrangement of the comb teeth causes the gas blown in through the air inlets to be divided into multiple streams, thereby forming multiple uniform reflux airflows for better powder fluidization.
[0004] Existing fluidization devices generally restrict the position of powder and airflow through pipe structure, so that the airflow carries the powder. Currently, the airflow direction is consistent with the direction of the pipe cavity, which requires a high gas flow rate to achieve the vulcanization effect, resulting in low efficiency. At the same time, existing fluidization devices cannot limit the speed at which the material enters the pipe cavity according to the gas flow rate, which will cause the material to accumulate inside the pipe cavity.

[0011] As a preferred embodiment of this utility model, the top diameter of the feed pipe is larger than the bottom diameter, and the unloading motor is fixedly connected to the feed pipe via a fixing frame;
[0012] As a preferred embodiment of this utility model, the drive shaft is located at the center of the feed pipe, and the drive shaft is rotatably connected to the limit frame through a limit bearing; the drive shaft can drive the auger to rotate.
[0013] As a preferred embodiment of this utility model, the diverter pipe passes through the limiting pipe and points towards the guide plate, and the diverter pipe is tangent to the wall of the limiting pipe. The tee is connected to the limiting pipe through the air inlet. The diverter pipe can guide the airflow to blow onto the guide plate.
[0014] As a preferred technical solution of this utility model, the diameter of the branch hole on the left side of the tee is the same as the diameter of the diversion pipe, and the diameter of the horizontal structure of the tee is larger than the diameter of the branch hole. The rear end of the tee is fixedly connected to the air outlet end of the fan. The tee can facilitate some airflow to enter the interior of the diversion pipe through the connecting hose.
[0015] Compared with the prior art, the present invention provides a pump chamber fluidization device, which has the following beneficial effects:
[0016] 1. This utility model utilizes an auger, which is fixedly installed on the outside of the drive shaft. When the drive shaft rotates, it drives the auger to rotate, causing the material to move downwards into the limiting tube. A flow meter monitors the gas flow rate inside the limiting tube and transmits the monitoring data to a PLC controller. The PLC controller calculates the gas flow rate and adjusts the speed of the unloading motor based on the calculation result. The unloading motor is fixed to the center of the feed pipe by a mounting bracket, allowing the material to easily enter the limiting tube. The unloading motor drives the auger to rotate via the drive shaft.

The diversion pipe passes through the limiting pipe and points towards the guide plate, and the walls of the diversion pipe and the limiting pipe are tangent. After the airflow generated by the blower enters the T-junction, part of the airflow will enter the diversion pipe through the connecting hose. Since the inner walls of the diversion pipe and the limiting pipe are tangent, the airflow will rotate along the wall of the limiting pipe under the guidance of the walls of the diversion pipe and the limiting pipe, and move to the right end of the limiting pipe after passing through the guide plate. Part of the airflow directly enters the limiting pipe horizontally through the T-junction and the air inlet. This method can generate a swirling flow inside the limiting pipe to facilitate the full fluidization of the material, thereby improving the material fluidization efficiency.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a pump fluidization device includes: a support frame 1, a limiting tube 11 fixedly installed inside the support frame 1, a flow meter 12 inserted through the upper left side of the limiting tube 11, a guide plate 13 fixedly installed at the left end of the limiting tube 11, a feed pipe 14 fixedly installed above the support frame 1, a fixing frame 15 fixedly installed at the top end of the feed pipe 14, a discharge motor 16 inserted through the fixing frame 15, a drive shaft 17 fixedly installed at the bottom end of the shaft of the discharge motor 16, and an auger 18 fixedly installed on the outside of the drive shaft 17. A limit frame 19 is fixedly installed at the bottom of 14. A limit bearing 110 is fixedly installed inside the limit frame 19. A diverter pipe 111 is fixedly installed on the front side of the left end of the limit tube 11. An air inlet 112 is fixedly installed on the left end of the limit tube 11. A tee 113 is fixedly installed on the left end of the air inlet 112. A connecting hose 114 is fixedly installed on one side of the tee 113. A fan 115 is fixedly installed at the rear end of the tee 113. A riser 116 is fixedly installed below the fan 115. A PLC controller 117 is fixedly installed above the riser 116.
[0027] The support frame 1 is symmetrically installed on the left and right sides of the limiting tube 11 with the center of the limiting tube 11 as the reference. A vertically upward branch is provided above the limiting tube 11. The diameter of the upper branch of the limiting tube 11 is smaller than the diameter of the lower horizontal structure. The guide plate 13 has a horizontal structure on the left and a spiral shape extending to the right on the right. The top diameter of the feed pipe 14 is larger than the bottom diameter. The unloading motor 16 is fixedly connected to the feed pipe 14 through the fixing frame 15. The drive shaft 17 is located in the middle of the feed pipe 14. The drive shaft 17 is rotatably connected to the limit frame 19 via the limit bearing 110. The diverter pipe 111 passes through the limit pipe 11 and points towards the guide plate 13. The diverter pipe 111 is tangent to the wall of the limit pipe 11. The tee 113 is connected to the limit pipe 11 via the air inlet 112. The diameter of the branch hole on the left side of the tee 113 is the same as the diameter of the diverter pipe 111. The diameter of the horizontal structure hole of the tee 113 is larger than the branch hole diameter. The rear end of the tee 113 is fixedly connected to the air outlet of the fan 115.
[0028] Specifically, the support frame 1 restricts the position of the limiting tube 11, thereby limiting the airflow direction and the position of the material to facilitate material movement. The flow meter 12, model VA550, monitors the gas flow rate inside the limiting tube 11 and transmits the monitoring data to the PLC controller 117, model PR10. The PLC controller 117 calculates the gas flow rate to adjust the speed of the unloading motor 16. The guide plate 13 guides the airflow to move to the right along the inner wall of the limiting tube 11. The feed pipe 14 facilitates the entry of material into the limiting tube 11. The unloading motor 16 is fixed to the center of the feed pipe 14 by the fixing frame 15. The unloading motor 16 drives the auger 18 to rotate via the drive shaft 17. The material discharge is adjusted by controlling the speed of the unloading motor 16. Speed, the limiting bracket 19 can limit the position of the bottom end of the drive shaft 17, and the limiting bearing 110 reduces the friction between the drive shaft 17 and the limiting bracket 19 when rotating. The air inlet 112 can facilitate the airflow generated by the fan 115 to enter the limiting tube 11 after passing through the tee 113. The tee 113 is connected to the diverter 111 through the connecting hose 114. After the airflow generated by the fan 115 enters the tee 113, part of the airflow will enter the diverter 111 through the connecting hose 114. Since the diverter 111 is tangent to the inner wall of the limiting tube 11, the airflow will rotate along the wall of the limiting tube 11 under the guidance of the walls of the diverter 111 and the limiting tube 11, and move to the right end of the limiting tube 11 after passing through the guide plate 13. Part of the airflow directly enters the limiting tube 11 horizontally through the tee 113 and the air inlet 112.
[0029] In use, the auger 18 is fixedly installed on the outside of the drive shaft 17. When the drive shaft 17 rotates, it drives the auger 18 to rotate, which in turn moves the material downward into the limiting tube 11. The flow meter 12 monitors the gas flow rate inside the limiting tube 11 and transmits the monitoring data to the PLC controller 117. The PLC controller 117 calculates the gas flow rate and adjusts the speed of the unloading motor 16 based on the calculation result. The unloading motor 16 is fixed to the center of the feed pipe 14 by the fixing bracket 15. The feed pipe 14 facilitates the entry of material into the limiting tube 11. The unloading motor 16 drives the auger 18 to rotate via the drive shaft 17. By controlling the speed of the unloading motor 16, the feeding speed is adjusted, thereby preventing the material from accumulating inside the limiting tube 11. The tee 113 is connected to the limiting tube 11 through the air inlet 112. The left side of the tee 113 is... The branch orifice diameter is the same as that of the diverter pipe 111, and the horizontal structure orifice diameter of the tee 113 is larger than that of the branch orifice diameter. The rear end of the tee 113 is fixedly connected to the air outlet end of the blower 115. The diverter pipe 111 passes through the limiting pipe 11 and points towards the guide plate 13. The diverter pipe 111 and the wall of the limiting pipe 11 are tangent. After the airflow generated by the blower 115 enters the interior of the tee 113, part of the airflow will enter the interior of the diverter pipe 111 through the connecting hose 114. Since the inner wall of the diverter pipe 111 is tangent to the inner wall of the limiting pipe 11, the airflow will rotate along the wall of the limiting pipe 11 under the guidance of the walls of the diverter pipe 111 and the limiting pipe 11, and move to the right end of the limiting pipe 11 after passing through the guide plate 13. Part of the airflow directly enters the interior of the limiting pipe 11 horizontally through the tee 113 and the air inlet 112. This method can generate a swirling flow inside the limiting pipe 11 to facilitate the full fluidization of the material, thereby improving the material fluidization efficiency.
