Description

Technical Field

[0001] This application relates to the technical field of industrial dust removal equipment, and in particular to a dust removal sealing installation structure for silo tops. Background Technology

[0002] In industrial production processes, silo top dust collectors are widely used for dust collection and purification in various silos. The sealed installation structure between the silo top dust collector and the silo top directly affects its dust collection efficiency and working environment.

[0003] Currently, most silo roofs are conical, and traditional sealing installation structures typically use simple flange connections supplemented by rubber gaskets for sealing. This structure has many drawbacks:

[0004] 1. Poor sealing effect: During long-term use, the rubber gasket is prone to aging and deformation, leading to dust leakage, which not only pollutes the working environment but may also cause safety hazards.

[0005] 2. Installation and disassembly are inconvenient. Traditional structures often require a lot of manpower and time to install and disassemble, which increases equipment maintenance costs.

[0006] 3. It is difficult to adapt to pressure changes under different working conditions. Under conditions of large pressure fluctuations, the sealing performance will decrease significantly.

[0007] 4. Some warehouse roofs are designed with a slope, which may lead to instability if a traditional structure is used.

[0008] Therefore, there is an urgent need to design a completely new sealed installation structure to solve these problems. Utility Model Content

[0009] In order to improve the problems of poor sealing effect, inconvenient installation and disassembly, and instability of the sealing installation structure of the silo top dust collector, this application provides a silo top dust collector sealing installation structure.

[0010] The technical solution for the dust removal and sealing installation structure on the top of a silo provided in this application is as follows:

[0011] A dust collector sealing installation structure for a silo top includes a dust collector body and a silo top body. The silo top body is characterized by: a vertically upward-extending support platform; an annular mounting boss extending upward from the support platform; a first connection opening at the connection between the annular mounting boss and the support platform; and an annular connecting boss extending upward from the inner side of the annular mounting boss. The bottom of the dust collector body has a second connection opening, the outer periphery of which extends downward to form an annular connecting flange. The connecting flange and the annular connecting boss are threaded together to form a sealing structure connecting the silo top body and the dust collector body. A support mounting frame is fixedly mounted on the upper surface of the silo top body, with the side of the support mounting frame abutting against the support platform.

[0012] By adopting the above technical solution, a stable structure of support platform-silo top body-support mounting frame is formed by setting up support platform and support mounting frame, which solves the problems of difficult installation on sloping silo top and subsequent structural instability; the connection structure of annular connecting boss and connecting flange is simple and can be installed by simply rotating the dust collector body. The use of threaded connection instead of flange reduces the number of parts, simplifies the installation process, and reduces processing costs.

[0013] Preferably, the main body of the support mounting frame is a steel plate frame, the upper surface of the support mounting frame is an installation platform, the installation platform is provided with installation guardrails on both sides, and the support mounting frame and the bottom of the silo top body are provided with ladders.

[0014] By adopting the above technical solution, and by setting up support mounting frames, mounting platforms, ladders and guardrails, the stability of the entire structure can be guaranteed while achieving convenient installation.

[0015] Preferably, the annular connecting boss has an annular sealing groove on its upper surface, an annular limiting protrusion at the bottom of the annular sealing groove, and an elastic sealing ring inside the annular sealing groove, the elastic sealing ring being disposed between the annular limiting protrusion and the groove wall of the annular sealing groove.

[0016] By adopting the above technical solution, the elastic sealing ring provides a basic seal, and the annular limiting protrusion makes the elastic sealing ring less likely to fall off.

[0017] Preferably, the lower surface of the connecting flange is provided with a sealing protrusion adapted to the annular sealing groove. The sealing protrusion is an annular protrusion, coaxial with the connecting flange, and forms a sleeve-type insertion structure with the annular sealing groove.

[0018] By adopting the above technical solution, it is ensured that the sealing ring is completely wrapped in the groove after installation, avoiding axial or radial displacement.

[0019] Preferably, a positioning guide assembly is provided between the annular connecting boss and the connecting flange. The positioning guide assembly includes a guide protrusion disposed on the outer periphery of the annular mounting boss and a guide sleeve disposed on the outer periphery of the connecting flange.

[0020] By adopting the above technical solution, the cooperation between the guide protrusion and the guide sleeve ensures that the coaxiality of the dust collector body is basically without error when it is lowered, avoids the sealing ring from being excessively compressed or failing locally due to unilateral bias, and ensures that the sealing ring is evenly stressed and deformed.

[0021] Preferably, the dust collector body is a bag pulse dust collector.

[0022] By adopting the above technical solutions, the bag filter pulse dust collector uses a PLC intelligent control system and pulse back-flushing technology to achieve "unattended" operation. Compared with electrostatic precipitators, bag filters have fewer auxiliary equipment, lower technical requirements, and lower initial investment.

[0023] Preferably, the outer casing of the dust collector body is provided with a rotating handle.

[0024] By adopting the above technical solution, the dust collector body can be rotated by turning the handle, saving effort.

[0025] Preferably, the support platform and the silo top body are provided with a silo top opening at the connection point. The support platform and the silo top body are connected by welding at the silo top opening, and the lower surface of the support mounting frame is welded to the upper surface of the silo top body.

[0026] By adopting the above technical solution, the support platform and the top of the silo, as well as the lower surface of the support mounting frame and the upper surface of the silo body, are connected by welding, which makes the overall structure stable.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By using a connection structure consisting of an annular connecting boss and a connecting flange, and replacing flanges with threaded connections, the number of parts is reduced, the installation process is simplified, and processing costs are lowered.

[0029] 2. By setting up a support platform and a support mounting frame to form a stable structure of support platform-silo roof body-support mounting frame, the problems of difficult installation on the sloping silo roof and subsequent structural instability are solved. At the same time, by setting up a support mounting frame, installation platform, ladder and guardrail, the stability of the entire structure can be guaranteed while achieving convenient installation.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a dust removal and sealing installation structure for a warehouse roof, referring to... Figure 1 It includes a dust collector body 1, a silo top body 2 and a support mounting frame 3. The silo top body 2 is a conical silo top. The silo top body 2 is provided with a vertically upward extending support platform 22. The horizontal cross section of the support platform 22 is rectangular. The dust collector body 1 is connected to the support platform 22 on the silo top body 2 through a sealing structure 4.

[0036] The support platform 22 and the silo roof body 2 are connected by a silo roof opening 21. The support platform and the silo roof body 2 are connected by welding at the silo roof opening 21. The lower surface of the support mounting frame 3 is welded to the upper surface of the silo roof body 2, and the side of the support mounting frame 3 abuts against the side of the support platform 22 to form a support structure. The main body of the support mounting frame 3 is a steel plate frame, which forms a stable structure with the support platform 22 and the silo roof body 2. An installation platform 31 is provided on the upper surface of the support mounting frame 3, and installation guardrails 311 are provided on both sides of the installation platform 31. A ladder 32 is provided on the side of the support mounting frame 3 away from the support platform 22. When installing the dust collector body 1, the staff can move to the installation platform 31 by climbing the ladder 32.

[0037] The dust collector body 1 is a bag pulse dust collector, which removes dust from the silo through bag pulse.

[0038] Reference Figure 2 and Figure 3The sealing structure 4 includes an annular mounting boss 41 extending vertically upward from the support platform 22 and an annular connecting flange 42 at the bottom of the dust collector body 1. A first connecting opening 221 is provided at the connection between the annular mounting boss 41 and the support platform 22. An annular connecting boss 411 extends upward from the inner side of the annular mounting boss 41, and an external thread 412 is provided on the outer peripheral wall of the annular connecting boss 411. A second connecting opening 12 is provided at the bottom of the dust collector body 1, and an internal thread 421 that mates with the external thread 412 is provided on the inner peripheral wall of the connecting flange 42. The connecting flange 42 and the annular connecting boss 411 are connected to form the sealing structure 4, connecting the silo top body 2 and the dust collector body 1. During installation, the dust collector body 1 can be rotated to connect the rotating dust collector body 1 and the annular mounting boss 41. An annular connecting boss 411 has an annular sealing groove 413 on its upper surface. An annular limiting protrusion 415 is located at the bottom of the groove. An elastic sealing ring 414 is disposed within the annular sealing groove 413, positioned between the annular limiting protrusion 415 and the groove wall of the annular sealing groove 413. This arrangement prevents the elastic sealing ring 414 from easily falling off. A sealing protrusion 422, adapted to the annular sealing groove 413, is located on the lower surface of the connecting flange 42. The sealing protrusion 422 is an annular protrusion, coaxial with the connecting flange 42, and forms a sleeve-type insertion structure with the annular sealing groove 413. When the sealing protrusion 422 contacts the elastic sealing ring 414 on the annular sealing groove 413, the external thread 412 and the internal thread 421 begin to mesh. As the external thread 412 and the internal thread 421 fully mesh, the elastic sealing ring 414 is completely enclosed within the annular sealing groove 413. A positioning guide assembly is provided between the annular connecting boss 411 and the connecting flange 42. The positioning guide assembly includes a guide protrusion 416 disposed on the outer periphery of the annular mounting boss 41 and a guide sleeve 423 disposed on the outer periphery of the connecting flange 42. The cooperation between the guide protrusion 416 and the guide sleeve 423 ensures that the coaxiality of the dust collector body 1 is basically without error when it is lowered, avoids the elastic sealing ring 414 from being excessively compressed or failing locally due to unilateral bias, and ensures that the elastic sealing ring 414 is evenly stressed and deformed.

[0039] The implementation process of the sealing installation of a dust removal sealing installation structure for silo tops according to an embodiment of this application is as follows:

[0040] The installer reaches the installation area via the support mounting frame 3, and uses a crane to place the dust collector body 1 into the installation area. The guide sleeve 423 of the dust collector body 1 is aligned with the guide protrusion 416 of the annular mounting boss 41, and the dust collector body 1 is lowered along the guide protrusion 416 so that the sealing protrusion 422 is inserted into the annular sealing mating groove 413. The dust collector body 1 is rotated by turning the handle 11 so that the internal thread 421 of the connecting flange 42 engages with the external thread 412 of the annular connecting boss 411 until the lower surface of the connecting flange 42 is in contact with the upper surface of the annular mounting boss 41.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
