Description

Technical Field

[0001] The present application relates to the technical field of fluidized bed dust removal equipment, and in particular to a portable fluidized bed dust collector. Background Art

[0002] Fluidized bed granulation is also known as boiling granulation or one-step granulation. It is a technology that puts the materials into a closed container at one time, mixes the materials evenly in the container, and then sprays the binder at a uniform speed through the equipment to allow the binder and materials to be fully mixed and flow in the container to form small particles. Hot air is sent in through the bottom to dry the wet particles, and finally the finished dry particles are directly collected.

[0003] During the entire fluidized granulation process, there is injection of high-temperature and high-pressure gas and exhaust gas discharge, thus forming a gas cycle. However, it should be noted that when the high-pressure gas is discharged, it will inevitably take away some of the materials that have been granulated into powder, causing material leakage. Therefore, most fluidized beds will be equipped with a dust collector at the gas discharge pipe outlet to filter out the dust materials carried away in the gas. Since the dust collector needs to be disassembled frequently for cleaning, the connection between the gas collecting pipe outlet and the exhaust pipe of the traditional dust collector is mostly detachable, such as a snap-on or threaded interface. However, after long-term use, the connection will no longer be tight, and there will be shaking problems. In addition, since the dust collector goes deep into the top of the hood of the fluidized bed, it is not convenient to disassemble and assemble the dust collector.

[0004] To this end, the present application provides a convenient fluidized bed dust collector, which makes the installation of the dust collector more convenient.

[0027] The following will be combined with the attached examples of the present application Figure 1-7 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0028] In order to solve the problems existing in the prior art, the present embodiment provides a portable fluidized bed dust collector, including a dust exhaust pipe 1 and two insert pipes 3, the side wall of the dust exhaust pipe 1 is provided with two connecting pipes 2, the upper end side wall of the insert pipe 3 is provided with a socket 7, the socket 7 is provided with a rubber ring 13, the bottom ends of the two connecting pipes 2 are respectively inserted into the corresponding insert pipes 3, a clamping piece is provided between the insert pipe 3 and the connecting pipe 2, a plurality of rings 5 ​​are arranged at the bottom end of the insert pipe 3, each ring 5 is provided with a dust filter bag 6, and the bottom ends of all dust filter bags 6 are commonly connected with an isolation layer.

[0029] Principle details of this embodiment:

[0030] A convenient fluidized bed dust collector comprises a dust exhaust pipe 1 and two insert pipes 3. The dust exhaust pipe 1 is inserted from the upper side wall of the fluidized bed cover. Two connecting pipes 2 are arranged on the side wall of the dust exhaust pipe 1 (in practice, the two connecting pipes 2 are retractable and driven by a hydraulic device to rise and fall, and this part of the structure is not shown in the attached drawings). A socket 7 is arranged on the upper side wall of the insert pipe 3, and a rubber ring 13 is arranged in the socket 7. The bottom ends of the two connecting pipes 2 are respectively inserted into the corresponding insert pipes 3. The insert pipes 3 are plugged into the connecting pipes 2. Compared with the connection by snap connection or connection through a threaded interface, the installation process is faster and more convenient. The rubber ring 13 is used to improve the tightness of the connection between the connecting pipe 2 and the insert pipe 3 to avoid air leakage at the connection. A clamping piece is provided between the insert pipe 3 and the connecting pipe 2 to improve the tightness of the connection between the insert pipe 3 and the connecting pipe 2.

[0031] The bottom end of the cannula 3 is provided with a plurality of collars 5, Figure 2As shown in the figure, there are three rings 5, and the specific number is limited according to the production product. A dust filter bag 6 is sleeved on the ring 5, and a tightening strap 14 is provided in the upper end of the dust filter bag 6 to tighten the dust filter bag 6 on the ring 5. The dust filter bag 6 is stretched and limited by the ring 5. The bottom ends of all dust filter bags 6 are connected to an isolation layer, which acts as a partition to separate the upper and lower connecting pipes 2 and the dusted materials.

[0032] When in use, first put the dust filter bags 6 on the ring 5 one by one, and then tighten the band 14 to fix it, so as to prevent the dust filter bags 6 from falling off the ring 5. After tightening the dust filter bags 6, hold the insert tube 3, plug the insert tube 3 and the port of the connecting pipe 2, and then open the partition and fix it. In this way, the high-pressure gas generated during the granulation process enters the dust filter bag 6 from the lower port of the dust filter bag 6, and then is discharged from the sieve holes on the side of the dust filter bag 6 into the isolated space on the upper layer of the partition, and then passes through the insert tube 3 and the connecting pipe 2 into the dust exhaust pipe 1 and is discharged outside the fluidized bed.

[0033] In this embodiment, in order to speed up the alignment of the insert tube 3 and the connecting tube 2, and then improve the plug-in efficiency of the insert tube 3 and the connecting tube 2, a conical bell mouth can be set on the outer wall of the lower end of the connecting tube 2 and the outer wall of the insert tube 3 located below the socket 7 to expand the docking range. As long as the bell mouths are aligned, they can be pushed up for alignment, thereby improving the installation efficiency.

[0034] In a further embodiment of the present scheme, the clamping member includes an elliptical plug 8 arranged at the top of the insert tube 3, and the side wall of the plug 8 has a plurality of wind grooves 10 in a circular array, each wind groove 10 is provided with an elastic sheet 9, and the bottom ends of all the elastic sheets 9 are fixedly connected in the insert tube 3, and the bottom end of the connecting tube 2 is provided with a circular cavity 12 that cooperates with the elastic sheet 9.

[0035] Principle details of this embodiment:

[0036] The clamping member includes an elliptical plug 8 disposed at the top of the insert tube 3, and the outer wall of the plug 8 is in contact with the inner wall of the connecting tube 2. The elliptical part of the plug 8 is located above the socket 7. The side wall of the plug 8 has a plurality of wind grooves 10 in an annular array, and each wind groove 10 is provided with an elastic sheet 9, and a supporting ring is welded to the bottom end of all the elastic sheets 9 in the insert tube 3. A circular cavity 12 is provided at the bottom end of the connecting tube 2 to cooperate with the elastic sheet 9. The circular cavity 12 is located above the connection between the connecting tube 2 and the socket 7.

[0037] When in use, after inserting the cannula 3 into the connecting tube 2, the high-pressure gas enters the cannula 3 through the filter dust bag 6, thereby impacting the support ring, causing the support ring to float upward, giving the cannula 3 an upward force, reducing the load pressure at the connection of the cannula 3; and the floating support ring will press the elastic sheet 9, causing the elastic sheet 9 to deform and lean against the inner wall of the circular cavity 12, forming a barrier between the cannula 3 and the connecting tube 2, increasing the resistance of the cannula 3 to fall. Until the input of high-pressure gas stops, the support ring is no longer impacted and falls, and the elastic sheet 9 is restored. At this time, the cannula 3 can be pulled down to separate the cannula 3 from the connecting tube 2.

[0038] In a further embodiment of the present invention, the inner wall of the rubber ring 13 is interference fit with the outer wall of the bottom end of the connecting tube 2, so that the rubber ring 13 and the side wall of the connecting tube 2 fit more closely, which can increase the connection strength between the inserting tube 3 and the connecting tube 2 and improve the airtightness of the connection between the inserting tube 3 and the connecting tube 2.

[0039] In a further embodiment of the present scheme, in order to ensure the tightness of the connection between the multiple rings 5 ​​and the cannula 3, an arc-shaped mounting frame 4 is fixed to the bottom end of the two cannula 3, and mounting rods are welded to both ends of the mounting frame 4 and the center of the arc, and the ring 5 is welded to the bottom end of the mounting rod.

[0040] In a further embodiment of the present invention, the two mounting frames 4 are provided with mutually abutting push rods 11 on opposite sides thereof. The two mounting frames 4 are abutted against each other by the push rods 11 to prevent the adjacent collars 5 from being damaged by the impact and shaking of the high-pressure gas.

[0041] In a further embodiment of the present invention, the plug 8 is detachably connected to the upper end of the insert tube 3, such as by threaded connection or by flange fasteners. The plug 8 and the insert tube 3 are not integrally formed, but are processed separately and then spliced, which reduces the production difficulty and also allows the plug 8 to be replaced after the elastic sheet 9 loses its elasticity, thus avoiding the waste of materials caused by overall replacement.

[0042] In a further embodiment of the present invention, the surface of the collar 5 is provided with a plurality of through holes and is hollowed out, the purpose of which is to reduce its own weight, thereby reducing the load pressure between the insertion tube 3 and the connecting tube 2. An interlayer 15 is provided inside the dust filter bag 6. The collar 5 is inserted into the dust filter bag 6 from the upper end of the dust filter bag 6, and after the binding band 14 is tightened, the collar 5 rests on the interlayer 15. The interlayer 15 is provided to prevent gas from leaking out from the hollow part of the collar 5 and affecting the dust filtering effect.

[0043] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
