Description

Technical Field

[0001] This utility model belongs to the technical field of dust collector blowpipes, and in particular relates to a dust collector blowpipe fixing device. Background Technology

[0002] As the core cleaning component of a pulse jet dust collector, the performance of the blowpipe directly affects the operating efficiency of the dust collection system and the service life of the filter bags. This device uses instantaneous pulses of high-pressure compressed air to create a strong reverse airflow inside the filter bags, effectively stripping and removing the dust layer adhering to the filter bag surface. During the cleaning process, compressed air is controlled by a pulse valve and passes through the blowpipe at extremely short intervals of 0.1-0.3 seconds. The air is then precisely guided to the filter bag opening through specially designed nozzles. This directional injection not only ensures the concentration and penetration of the cleaning airflow but also creates instantaneous pressure waves inside the filter bags, causing high-frequency micro-vibrations and further enhancing the cleaning effect. The blowpipe needs to be supported within the housing by a supporting structure, but it still has the following drawbacks in actual use:

[0003] During the blowing process of the blowpipe, air is directly delivered into the housing and connected to the housing through a single supporting structure. The single fixed structure set in the fixed housing will result in insufficient stability and affect the stability of the blowing.

[0004] Secondly, the blowpipe is fixed inside the housing and uses a pulse valve to deliver air in pulses. The blowpipe is supported by a support structure, which will impact the housing. After the impact, the spraying stability of the water pipe will be affected. Utility Model Content

[0005] The purpose of this utility model is to provide a dust collector blowpipe fixing device. By setting a fixing shell, blowpipe body, support components and support sleeve, it solves the problem that the blowpipe fixing device uses a single fixing structure for fixing support, which easily affects the blowing stability and the blowpipe impact can easily damage the support structure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a dust collector blowpipe fixing device, comprising a fixing shell, a blowpipe body, support components, and a support sleeve. Three support components are fixed along a center line parallel to the long side at the bottom of the fixing shell. Each support component includes a clamp, a fixing post, an elastic sleeve, and an elastic post. Two clamps are arranged symmetrically vertically. The blowpipe body is arranged between all the symmetrical clamps in the support components. A fixing post is fixed at the center of the outer arc surface of the lower clamp. An elastic sleeve is fixed at the bottom edge of the fixing post, and an elastic post is fixed at the center of the bottom end of the fixing post. One end of the blowpipe body is fixedly connected to an L-shaped transfer pipe. The top end of the transfer pipe extends beyond the top of the fixing shell. A support sleeve is fixed at the top of the fixing shell outside the transfer pipe. During operation, the blowpipe body and support components are supported within the fixing shell. After the pulse valve generates pulsed airflow, the airflow is delivered to the nozzle and ejected through the nozzle. The support components support the blowpipe body at the bottom of the fixing shell, and the support sleeve supports the transfer pipe at the top of the fixing shell.

[0008] Furthermore, a box support square steel is fixed to both short sides of the bottom of the fixed shell, and several spray nozzles are opened at the bottom of the fixed shell between the two box support square steels. The support square steel at the bottom of the fixed shell is supported on the bag filter, and the spray nozzles deliver the air sprayed from the nozzles to the spray nozzles.

[0009] Furthermore, a support plate is fixed to one end of the blowpipe body away from the transfer pipe, and the bottom end of the support plate is fixed to the inner bottom of the fixed shell. Each blowpipe body above the blowpipe nozzle is fixedly connected to a nozzle at equal intervals on the lower periphery. The support plate on the blowpipe body supports the blowpipe body, and the nozzle delivers the air in the blowpipe body to the fixed shell.

[0010] Furthermore, the support assembly also includes mounting bolts and fastening nuts. The two clamps included in the same support assembly are vertically and movably connected to the same end by mounting bolts. The mounting bolts extend out of the upper clamp end and are threadedly connected to fastening nuts. The mounting bolts and fastening nuts on the support assembly cooperate to secure the blowpipe body.

[0011] Furthermore, the support assembly also includes a fixing sleeve, the bottom end of the elastic column is fixed to the bottom of the fixing sleeve, the bottom end of the elastic sleeve is fixed to the top of the fixing sleeve, the elastic column is in a compressed state inside the fixing sleeve and the elastic sleeve, the bottom end of the fixing sleeve is fixed to the bottom of the fixing shell, and the bottom end of the fixing sleeve is disposed between the spray nozzles. When the support assembly is in operation, the fixing sleeve connects the elastic column and the fixing sleeve.

[0012] Furthermore, a support ring is fixed in the middle of the support sleeve, the support ring is fixed around the transfer tube, and a pulse valve is fixedly connected to the top of the transfer tube. The support sleeve supports the transfer tube at the top of the fixed shell through the support ring, and the pulse valve delivers pulsed airflow into the transfer tube.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of unstable blowing caused by a single fixed structure in the fixing device of the blowpipe body, by setting up a fixed shell, a blowpipe body, and support components. After the pulse valve is opened, the pulse airflow is delivered to the transfer pipe, and then to the blowpipe body. Inside the blowpipe body, it is delivered to the nozzle, and then evenly blown into the nozzle at the bottom of the fixed shell. Finally, it is sprayed into the bag filter dust collector. The support plate at the end of the blowpipe body fixes and supports the end of the blowpipe body inside the fixed shell. At the same time, three support components are set around the blowpipe body to provide good support. Multiple support points are set around the blowpipe body to ensure that the blowing operation is carried out well through the fixed shell during operation and to prevent the blowpipe body from having too large a blowing force that affects the blowing stability, thus ensuring good blowing stability.

[0015] This invention solves the problem of damage to the support structure caused by the impact of the jetting of the jetting pipe body by setting up a fixed shell, a jetting pipe body, a support component, and a support sleeve. When the pulse valve is opened, the pulsed airflow generated by the pulse valve is delivered to the transfer pipe, and then to the jetting pipe body. The jetting pipe body delivers the airflow to the nozzle and sprays it out. When the air is sprayed out in the nozzle, it impacts the clamp. When the jetting impact is transmitted to the clamp, the elastic column and elastic sleeve connected to the fixed column cooperate to reduce the impact of the jetting pipe body on the bottom of the fixed shell, thereby reducing the impact of the jetting of the jetting pipe body on the fixed shell and preventing damage to the support structure caused by the jetting impact of the jetting pipe body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-5This utility model is a dust collector blowpipe fixing device, including a fixing shell 1, a blowpipe body 2, support components 3, and support sleeves 4. Three support components 3 are fixed inside the fixing shell 1 along a center line parallel to the long side. The fixing shell 1 supports the blowpipe body 2 within the fixing shell 1 via the support components 3. Each support component 3 includes a clamp 301, a fixing post 304, an elastic sleeve 305, and an elastic post 307. Two clamps 301 are arranged symmetrically vertically. The blowpipe body 2 is arranged between all the symmetrical clamps 301 included in the support components 3. A fixing post 304 is fixed to the center of the outer arc surface of the lower clamp 301. An elastic sleeve 305 is fixed to the bottom edge of the fixing post 304. An elastic column 307 is fixed at the center of the end, and two clamps 301 are clamped on the main body 2 of the blowpipe, so that the support component 3 connects the main body 2 of the blowpipe. At the same time, the fixed column 304 on the clamp 301 connects the elastic column 307 and the elastic sleeve 305, so that the elastic sleeve 305 is in a tensile state during operation. The compression of the elastic sleeve 305 provides stable support for the main body 2 of the blowpipe, and the elastic column 307 buffers the blowpipe body 2. One end of the blowpipe body 2 is fixedly connected to an L-shaped transfer pipe 201. The transfer pipe 201 delivers the pulsed airflow output by the pulse valve 5 to the blowpipe body 2. The top end of the transfer pipe 201 extends out of the top of the fixed shell 1. A support sleeve 4 is fixed on the top of the fixed shell 1 outside the transfer pipe 201. The support sleeve 4 supports the transfer pipe 201 above the fixed shell 1.

[0027] Specifically, two short sides of the bottom of the fixed shell 1 are fixed with box support square steel 102. Several blowing ports 101 are opened at the bottom of the fixed shell 1 between the two box support square steel 102. After the support square steel on the fixed shell 1 is fixed in the installation position of the bag dust collector, the blowing ports 101 on the fixed shell 1 will discharge air.

[0028] Furthermore, a support plate 202 is fixed to the end of the blowpipe body 2 away from the transfer pipe 201. The bottom end of the support plate 202 is fixed to the inner bottom of the fixed shell 1. Each blowpipe body 2 above the blowpipe nozzle 101 is fixedly connected to a nozzle 203 at equal intervals on the lower part of its periphery. The support plate 202 on the blowpipe body 2 supports the end of the blowpipe body 2 away from the transfer pipe 201. The nozzle 203 sprays pulsed airflow into the blowpipe nozzle 101. The spray direction of each nozzle 203 coincides with the central axis of the blowpipe nozzle 101.

[0029] The operation process of this embodiment is as follows: During operation, when the pulse valve 5 is opened, the pulse airflow is delivered to the transfer pipe 201, and then delivered to the main body 2 of the blowpipe through the transfer pipe 201. In the main body 2 of the blowpipe, it is delivered to the nozzle 203. The nozzle 203 evenly sprays the airflow into the bag dust collector through the nozzle 101. The support plate 202 at the end of the main body 2 of the blowpipe fixes and supports the end of the main body 2 of the blowpipe in the fixed shell 1. At the same time, three support components 3 are also provided around the main body 2 of the blowpipe to provide good support for the main body 2 of the blowpipe. Multiple support points are provided around the main body 2 of the blowpipe so that the blowing operation can be carried out well through the fixed shell 1 during operation, and prevent the blowpipe main body 2 from having a large blowing force that affects the blowing stability. Specific Implementation Example 2

[0030] Please see Figure 1-6 Based on the first specific embodiment, the support component 3 further includes a mounting bolt 302 and a fastening nut 303. The ends of the two clamps 301 included in the same support component 3 are vertically and movably connected to the mounting bolt 302. The mounting bolt 302 extends out of the upper clamp 301 and is threadedly connected to the fastening nut 303. When the support component 3 is in operation, the mounting bolt 302 is inserted into the two clamps 301 and extends out of the upper clamp 301. Then, the fastening nut 303 is screwed onto the fastening nut 303 until the two clamps 301 included in the same support component 3 are fastened to the blowpipe body 2. The support component 3 and the blowpipe body 2 are then fastened together.

[0031] Specifically, the support assembly 3 also includes a fixed sleeve 306. The bottom end of the elastic column 307 is fixed to the bottom of the fixed sleeve 306, and the bottom end of the elastic sleeve 305 is fixed to the top of the fixed sleeve 306. The elastic column 307 is in a compressed state within the fixed sleeve 306 and the elastic sleeve 305. The bottom end of the fixed sleeve 306 is fixed to the bottom of the fixed shell 1. The bottom end of the fixed sleeve 306 is located between the nozzles 101. The fixed sleeve 306 included in the support assembly 3 is fixed to the bottom of the fixed shell 1. The elastic column 307 is in a compressed state. The compressed elastic column 307 pushes the fixed column 304, causing the elastic sleeve 305 to be in a taut state, thus buffering the pressure generated by the blowpipe body 2. The elastic column 307 absorbs the vertical impact force through compression, and the elastic sleeve 305 restricts the lateral vibration of the blowpipe body 2 through stretching.

[0032] Furthermore, a support ring 401 is fixed in the middle of the support sleeve 4. The support ring 401 is fixed around the transfer pipe 201. A pulse valve 5 is fixedly connected to the top of the transfer pipe 201. The support ring 401 inside the support sleeve 4 provides auxiliary support for the transfer pipe 201 that extends out of the fixed shell 1. The input end of the pulse valve 5 is connected to the pipeline for conveying high-pressure air, and the high-pressure air pulse is delivered to the transfer pipe 201.

[0033] The operation process of this embodiment is as follows: During operation, the pulse valve 5 is opened, and the pulse airflow generated by the pulse valve 5 is delivered to the transfer pipe 201 and then to the main body of the blow pipe 2 through the transfer pipe 201. The airflow is then delivered to the nozzle 203 through the main body of the blow pipe 2 and ejected. Air is ejected from the nozzle 203 and impacts the clamp 301 during operation. When the impact of the blow is transmitted to the clamp 301, the elastic column 307 and elastic sleeve 305 connected to the fixing column 304 cooperate to reduce the impact of the blow pipe main body 2 on the bottom of the fixing shell 1 and reduce the impact of the blow from the blow pipe main body 2 on the fixing shell 1.
