Technical Field

[0001] This utility model relates to the field of silo pump technology, and in particular to an integrated fluidization device for a bottom-feed silo pump. Background Technology

[0002] A silo pump, also known as a silo-type pump, is a relatively reliable dense-phase dynamic pressure pneumatic conveying device for transporting powdery materials under high pressure.

[0003] A search revealed Chinese patent CN110092204B, which discloses a bottom-feed silo pump integrated fluidization device, including a pump body and a delivery pipe, and addresses the issue of improving fluidization efficiency within the pump body. However, it still suffers from the following drawback: during operation, larger particles tend to accumulate at the bends in the delivery pipe, affecting the overall fluidization efficiency of the pump. To better address these issues, promote technological advancements in the industry, and enhance core competitiveness, this application proposes a novel structural design that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bottom-feed silo pump integral fluidization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bottom-feed silo pump fluidization device includes a silo pump body. A connecting pipe is fixedly connected to the bottom outlet of the silo pump body. A discharge pipe is fixedly connected to the bottom end of the connecting pipe. A first slide rod is movably connected to the bottom of the discharge pipe. A through groove is opened inside the first slide rod. Multiple through holes communicating with the through groove are opened on the first slide rod. A power component for driving the first slide rod to move up and down is provided at the bottom of the discharge pipe. Two fixed rods are fixedly connected to one inner wall of the discharge pipe. A housing is fixedly connected between one end of the two fixed rods. A second slide rod is movably connected inside the housing. Movable rods are fixedly connected to the outer sides of both the second slide rod and the first slide rod. A guide component is provided between the housing and the first and second slide rods. A pushing component for moving the second slide rod laterally is provided on one side of the first slide rod.

[0007] As a further embodiment of this utility model, the power assembly includes a fixed frame, which is fixed to the bottom outer wall of the discharge pipe by bolts. A cylinder is fixedly connected to the bottom of the fixed frame, and one end of the cylinder piston rod passes through the fixed frame and is fixed to the first sliding rod.

[0008] As a further embodiment of this utility model, a flexible hose is fixedly connected to one end of the first slide rod extending out of the discharge pipe.

[0009] As a further embodiment of this utility model, the guide assembly includes multiple guide blocks, one of which is fixed to one side of the first slide rod, and the other two guide blocks are respectively fixed to the top and bottom of the second slide rod. The top and one side of the housing are provided with sliding grooves, and the guide blocks are slidably connected to the sliding grooves at the corresponding positions.

[0010] As a further embodiment of this utility model, the pushing component includes a fixing plate, which is welded to one side of the first slide rod. An inclined rod is fixedly connected to the upper surface of the fixing plate. A groove adapted to the inclined rod is opened on the second slide rod, and the inclined rod passes through the groove and is slidably connected to the groove.

[0011] As a further embodiment of this invention, the fixing plate and the diagonal rod are located inside the housing.

[0012] As a further embodiment of this utility model, the first slide bar and the plurality of movable rods connected thereto are located inside the connecting pipe, and the second slide bar and the plurality of movable rods connected thereto are located inside the discharge pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model solves the problem of material caking in the bottom pipe of the silo pump body, which leads to poor conveying, by the synergistic effect of mechanical agitation and airflow fluidization. It reduces the resistance of material in the conveying process, improves the conveying efficiency and stability of powder materials, and improves the discharge effect of the device.

[0015] 2. By pushing the component, the second slide bar drives the connected moving rod to move horizontally left and right. In this way, the moving rod has both up-and-down stirring action and horizontal stirring action in the discharge pipe, which further enhances the stirring and unblocking effect of the material in the discharge pipe, avoids material blockage in the discharge pipe, and makes the entire conveying process more stable.

[0016] 3. By setting up the guide component, the second slide bar is guided during the movement, thereby enabling the second crossbar to move laterally stably and improving the effectiveness of the device. Attached Figure Description

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4 A bottom-feed silo pump fluidization device includes a silo pump body 1, a connecting pipe 2 is fixedly connected to the bottom outlet of the silo pump body 1, and a discharge pipe 3 is fixedly connected to the bottom end of the connecting pipe 2. The material in the silo pump body 1 is discharged sequentially through the connecting pipe 2 and the discharge pipe 3.

[0024] The bottom of the discharge pipe 3 is slidably connected to a first slide rod 4. The first slide rod 4 has a through groove 17 inside and multiple through holes 18 communicating with the through groove 17. A one-way valve is installed in the through hole 18. External high-pressure gas enters the through groove 17 of the first slide rod 4. The gas pressure is greater than the pressure required to open the one-way valve. Finally, it is discharged through the multiple through holes 18, so that the material at the connection between the connecting pipe 2 and the discharge pipe 3 is fluidized, reducing the conveying resistance.

[0025] In particular, the bottom of the discharge pipe 3 is provided with a power assembly that drives the first slide rod 4 to move up and down. The power assembly includes a fixed frame 8, which is fixed to the bottom outer wall of the discharge pipe 3 by bolts. A cylinder 10 is fixed to the bottom of the fixed frame 8 by bolts. One end of the piston rod of the cylinder 10 passes through the fixed frame 8 and is fixed to the first slide rod 4. A silicone sealing gasket is sleeved at the connection between the first slide rod 4 and the discharge pipe 3.

[0026] Two fixing rods 6 are fixed to one side of the inner wall of the discharge pipe 3 by bolts. A housing 7 is fixed between one end of the two fixing rods 6 by bolts. A second sliding rod 11 is slidably connected inside the housing 7. Multiple moving rods 5 are fixed to the outside of the second sliding rod 11 and the first sliding rod 4 by bolts.

[0027] It should be noted that a pushing assembly for the second slide rod 11 to move laterally is provided on one side of the first slide rod 4. The pushing assembly includes a fixed plate 14, which is welded to one side of the first slide rod 4. An inclined rod 12 is welded to the upper surface of the fixed plate 14. A groove 15 adapted to the inclined rod 12 is provided on the second slide rod 11. The cross section of the groove 15 is a parallelogram. The inclined rod 12 passes through the groove 15 and is slidably connected to the groove 15.

[0028] When the first slide bar 4 moves up and down, the fixed plate 14 drives the inclined bar 12 to move up and down along the trough 15 and squeezes the trough 15, thereby causing the second slide bar 11 and the moving rod 5 to move laterally left and right, so that the moving rod 5 further agitates the material in the discharge pipe 3 and avoids blockage.

[0029] The housing 7 is equipped with a detachable lower cover. The fixing plate 14 and the inclined rod 12 are located inside the housing 7. When the first sliding rod 4 moves, the inclined rod 12 will not detach from the groove 15.

[0030] In this utility model, the top and one side of the housing 7 are provided with sliding grooves 13, and a guide assembly is provided between the housing 7 and the first sliding rod 4 and the second sliding rod 11. The guide assembly moves within the sliding groove 13.

[0031] The guide assembly includes a plurality of guide blocks 16, one of which is fixed to one side of the first slide bar 4;

[0032] The other two guide blocks 16 are fixed on both sides of the second slide rod 11 respectively;

[0033] The guide block 16 is slidably connected to the corresponding slide groove 13. Through the cooperation of the guide block 16 and the slide groove 13, the second slide rod 11 is guided, thereby enabling the second slide rod 11 to move laterally stably.

[0034] The cylinder 10 extends and retracts, causing the first slide rod 4 to move the connected moving rod 5 up and down. At the same time, the movement of the first slide rod 4 drives the second slide rod 11 to move through the housing 7, thereby causing the multiple moving rods 5 connected to the second slide rod 11 to move up and down, so that the moving rods 5 squeeze the material in the connecting pipe 2 and the discharge pipe 3.

[0035] When the cylinder 10 is retracted to its shortest length, the inclined rod 12 will not detach from the groove 15. When the cylinder 10 is extended to its longest length, the fixing plate 14 contacts the lower surface of the second sliding rod 11.

[0036] The first slide bar 4 and the multiple movable rods 5 connected thereto are located inside the connecting pipe 2, and the second slide bar 11 and the multiple movable rods 5 connected thereto are located inside the discharge pipe 3;

[0037] One end of the first slide bar 4 extending out of the discharge pipe 3 is connected to a fixed hose 9. The hose 9 is connected to an external air supply device, and the high-pressure gas in the external air supply device enters the through groove 17 of the first slide bar 4 through the hose 9.

[0038] Working principle: When materials need to be conveyed, the materials in the silo pump body 1 are discharged through the connecting pipe 2 and the discharge pipe 3;

[0039] Connect hose 9 to the external air supply device;

[0040] When the cylinder 10 is activated, its extension and retraction cause the first slide rod 4 to move the connecting rod 5 up and down. At the same time, the movement of the first slide rod 4 drives the second slide rod 11 to move through the housing 7, thereby causing the multiple connecting rods 5 connected to the second slide rod 11 to move up and down, so that the connecting rods 5 squeeze the material in the connecting pipe 2 and the discharge pipe 3.

[0041] Meanwhile, the high-pressure gas in the external gas supply device enters the through groove 17 of the first slide bar 4 through the hose 9, and finally exits through multiple through holes 18, so that the material at the connection between the connecting pipe 2 and the discharge pipe 3 is fluidized, reducing the conveying resistance.

[0042] At the same time, the first slide bar 4 moves up and down, causing the fixed plate 14 to drive the inclined bar 12 to move up and down along the trough 15, thereby causing the second slide bar 11 to drive the moving rod 5 connected to it to move laterally left and right. Meanwhile, the guide block 16 and the trough 13 guide the second slide bar 11, so that the moving rod 5 further agitates the material in the discharge pipe 3, further preventing blockage.

[0043] This utility model has been described through the above embodiments. Those skilled in the art will understand that this utility model is not limited to the above embodiments. Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
