Description

Technical Field

[0001] The utility model relates to the field of dust bag connection and installation, in particular to a dust bag connection structure. Background Art

[0002] Dust bags are non-woven or woven fabrics that are sewn or hot-melted into bag-shaped filter bags of certain specifications. They are one of the important environmental protection accessories for filtering, collecting dust and collecting materials. They are the main components of bag dust collectors and bag dust collectors. They have the characteristics of high temperature resistance, high strength, acid and alkali corrosion resistance, wear resistance, and folding resistance. After different surface chemical treatments and finishing technologies, they also have the functions of easy dust cleaning, water and oil repellency, and anti-static. They are dimensionally stable, have better strength, and are cheaper than other high temperature resistant chemical fibers.

[0003] At present, when the bag filter is filtering, the filtering airflow flows from the upper part of the filter bag to the inside of the filter bag, and flows out to the outside of the bag after being filtered by the bag filter layer. Therefore, the filtered dust particles will adhere to the inner wall surface of the filter bag to form a dust layer. After the dust bag has been running for a long time, the dust layer accumulated on the dust-facing surface inside the dust bag will become thicker and thicker, which will increase the resistance loss of the dust collector. Therefore, after the bag filter has been running for a period of time, it is necessary to clean the dust, that is, to clean the dust attached to the surface of the dust bag. In view of the fact that the existing dust bag cleaning mostly adopts pulse jet cleaning, which is easy to cause damage to the dust bag, based on this, the applicant has specially proposed a back-blowing cleaning dust collector, that is, to reversely blow the dust bag through the back-blowing airflow to achieve the cleaning of the dust attached to the surface of the dust bag.

[0004] When this back-blowing cleaning method is used, since the dust bags are mostly fixedly installed, when the back-blowing airflow back-blows the dust on the surface of the dust bags, some dust is still difficult to be completely cleaned, thus affecting its cleaning effect. Utility Model Content

[0005] The utility model aims to provide a dust bag connection structure for solving one of the above problems.

[0006] The utility model is realized by the following technical solutions:

[0007] A dust bag connection structure, comprising a dust bag located in a dust removal chamber, wherein the length direction of the dust bag is parallel to the axial direction of the dust removal chamber, and the dust bag is connected to a partition in the dust removal chamber through an elastic locking mechanism at its upper end, wherein a plurality of through holes adapted to the top of the dust bag are formed on the partition;

[0008] The elastic locking mechanism includes at least one group of elastic telescopic parts, and the elastic telescopic parts are located inside the dust bag and arranged along its axial direction. The elastic telescopic parts include a threaded adjustment rod and a connecting spring. The top end of the threaded adjustment rod is movably connected to the through hole on the partition through a hook buckle, and the bottom end is connected to the connecting part inside the dust bag through a connecting spring.

[0009] Preferably, the threaded adjustment rod includes a sleeve and a screw, the interior of the sleeve is hollow and the bottom is open, the screw is coaxially arranged inside the sleeve, and the top of the screw is slidably matched with the inside of the sleeve through a slider, and a threaded ring is rotatably provided at the bottom opening of the sleeve, and the threaded ring is consistent with the screw thread. At the same time, by setting the threaded adjustment rod, after the dust bag is installed, its length can be freely adjusted according to actual conditions, and then after its length changes, the connecting spring is stretched or compressed to adjust its elastic strength, so that after the dust bag is subjected to the reverse suction wind force, it can produce corresponding elastic deformation according to the reverse suction wind force, thereby shaking the inside of the dust bag, so that the dust particles inside it can fall off, and the length adjustment change of the threaded adjustment rod is also conducive to its operators to adapt and install dust bags of different lengths.

[0010] Furthermore, there are multiple elastic expansion members, and the multiple elastic expansion members are arranged in a circular array inside the dust bag, so that when the dust bag is subjected to reverse suction wind force, the inner wall of the dust bag can be shaken in the circumferential direction driven by the multiple elastic expansion members, so that the dust particles around the inside of the dust bag can fall off through shaking.

[0011] Specifically, there are multiple connectors corresponding to the elastic telescopic parts, and the multiple connectors are distributed in a ring array. The connectors are concave arc-shaped, and their two ends are connected to the inner wall of the dust bag through hook fasteners, and any two adjacent connectors are connected by telescopic springs. It should be noted here that since the reverse suction fan sucks the inside of the dust bag, its deformation mainly changes from a "full" state to a "sucked" state, that is, when the inner wall is deformed, it shrinks from the surroundings to the middle. Therefore, in order to facilitate its shrinkage and deformation, this solution provides multiple connectors, and a telescopic spring is provided between two adjacent connectors, so that when the inside of the dust bag shrinks to the middle (i.e. "sucked"), the surroundings can be subjected to corresponding tension, so that it shakes evenly.

[0012] Preferably, a limit protection mechanism is further provided between the slider and the inner wall of the sleeve, and the limit protection mechanism includes a plurality of elastic limit rods arranged around the outer periphery of the slider, and limit grooves arranged corresponding to the elastic limit rods and equidistantly distributed from top to bottom on the inner wall of the sleeve. The above arrangement facilitates the operator to position and limit the adjustment stroke of the threaded adjustment rod when adjusting the length of the threaded adjustment rod, and avoids damage to the threaded adjustment rod due to excessive adjustment.

[0013] Preferably, a movable part is provided between the threaded adjustment rod and the hook fastener, and the movable part includes: a connecting tube and a plug rod, the top of the plug rod is fixedly connected to the hook fastener, the connecting tube is hollow inside and open at the top, a blocking ring is provided around the top opening of the connecting tube, the bottom end of the plug rod extends into the connecting tube, and slides with the connecting tube through an anti-slip head, and an elastic hydraulic rod is also provided in the anti-slip head. Based on the above structure, when the dust bag is back-sucking and cleaning, that is, when the dust bag is deformed and shaken inside, the dust bag as a whole can also be pulled by the back-sucking wind force, and the movable part causes the dust bag as a whole to shake up and down in a vertical direction, thereby promoting the shaking and dropping of dust particles.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0015] 1. This scheme installs the dust bag in the dust removal chamber by setting an elastic locking mechanism, which is movably connected to the partition through the elastic locking mechanism, so that when the reverse suction cleaning is performed, after the reverse suction fan works to generate reverse suction wind force, the dust bag is sucked, and the inside of the dust bag can be shaken and deformed through the elastic locking mechanism, thereby promoting the shaking and falling of dust on the dust-facing surface inside the dust bag, thereby promoting the cleaning operation of the dust bag, making the dust bag cleaning and dust removal more thorough and avoiding dust particles from remaining;

[0016] 2. This scheme sets a threaded adjustment rod. After the dust bag is installed, its length can be freely adjusted according to the actual situation. After its length changes, the connecting spring is stretched or compressed to adjust its elastic strength, so that after the dust bag is subjected to the reverse suction wind force, it can produce corresponding elastic deformation according to the reverse suction wind force, thereby shaking the inside of the dust bag to facilitate the dust particles inside to fall off. The length adjustment of the threaded adjustment rod is also conducive to the operator to adapt the installation of dust bags of different lengths and sizes, thereby improving its use effect.

[0017] 3. The utility model further provides movable parts. When the dust bag is back-sucking and cleaning, that is, when the dust bag is deformed and shaken inside, the dust bag as a whole can be pulled by the back-sucking wind force to make the dust bag as a whole shake up and down in a vertical direction through the movable parts, thereby promoting the dust particles to be shaken off and making the dust bag cleaning more thorough.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0029] In order to make the technical solution of the present application clearer and easier for technicians to understand, the installation position of the dust bag of the present solution is explained here. As we all know, the dust bag is the core component of the bag dust collector, and its installation position is in the dust removal chamber in the dust collector, such as Figure 1 shown.

[0030] Embodiment 1;

[0031] Please refer to the attached Figures 1 to 5 A dust bag connection structure includes a dust bag 1 located in a dust removal chamber, wherein the length direction of the dust bag 1 is parallel to the axial direction of the dust removal chamber, and the dust bag 1 is connected to a partition in the dust removal chamber through an elastic locking mechanism 2 at its upper end, and the partition is provided with a plurality of through holes adapted to the top of the dust bag 1;

[0032] The elastic locking mechanism 2 includes at least one group of elastic telescopic parts, and the elastic telescopic parts are located inside the dust bag 1 and arranged along its axial direction. The elastic telescopic parts include a threaded adjustment rod 20 and a connecting spring 21. The top end of the threaded adjustment rod 20 is movably connected to the through hole on the partition through a hook fastener, and the bottom end is connected to the connecting part 3 inside the dust bag 1 through the connecting spring 21.

[0033] It should be noted that the present scheme is based on a reverse suction dust collector. When the dust collector bag 1 is reversely suctioned and cleaned, the inside of the dust collector bag 1 is sucked by the reverse suction wind force, and can be shaken and deformed through the elastic locking mechanism 2, so as to facilitate the shaking and falling of dust particles on the dust facing surface thereof. Specifically, after the dust collector bag 1 is subjected to the reverse suction wind force, its interior will be converted from a "full" state to a "deflated" state, and the elastic telescopic part can be pulled therein, so that through the elastic connection of the elastic telescopic part, the dust collecting bag 1 has its internal dust facing surface deformed and shaken during the reverse suction, so as to facilitate the falling of dust particles, thereby facilitating the reverse suction of the cleaning unit, thereby making the cleaning and dust removal operation of the dust collector bag 1 more thorough and avoiding residual dust particles.

[0034] Based on the above embodiment, a preferred implementation of the threaded adjustment rod 20 is proposed here, such as Figure 4It includes a sleeve 200 and a screw rod 201. The interior of the sleeve 200 is hollow and the bottom is open. The screw rod 201 is coaxially arranged inside the sleeve 200, and the top of the screw rod 201 is slidably matched with the inside of the sleeve 200 through a slider 202. A threaded ring 203 is rotatably provided at the bottom opening of the sleeve 200. The threaded ring 203 is threadedly matched with the screw rod 201, which is convenient for operators to rotate the threaded ring 203, so that after the rotation, the screw rod 201 is driven to move freely in the sleeve 200 through the slider 202. It is hoped that after the dust bag 1 is installed, the operator can freely adjust its length according to actual conditions. After its length changes, the connecting spring 21 is stretched or compressed to adjust its elastic strength, so that after the dust bag 1 is subjected to the back-suction wind force, it can produce corresponding elastic deformation according to the back-suction wind force, thereby shaking the inside of the dust bag 1 to facilitate the falling of dust particles therein. Moreover, the length adjustment change of the threaded adjustment rod 20 is also convenient for the operator to adapt the installation of dust bags 1 of different lengths.

[0035] Based on the above embodiment, when the dust bag 1 is back-sucking and cleaning, that is, after the dust bag 1 is sucked, its deformation mainly changes from a "full" state to a "sucked" state, that is, when the inner wall is deformed, it shrinks from the surrounding to the middle. Therefore, in order to facilitate its shrinkage deformation, Figure 5 , the present scheme further preferably provides a plurality of elastic connecting members 3, and the plurality of elastic connecting members 3 are distributed in the dust bag 1 in an annular array, so that when the dust bag 1 is subjected to the reverse suction wind force, the circumferential direction of the inner wall thereof can all generate shaking under the drive of the plurality of elastic telescopic members; correspondingly, when a plurality of elastic telescopic members are provided, a plurality of connecting members 3 are also correspondingly provided in an annular array and are connected with the elastic telescopic members one by one, and for the connecting member 3, a preferred implementation manner is as follows: the connecting member 3 is in a concave arc shape, and its two ends are connected to the inner wall of the dust bag 1 through hook fasteners, and any two adjacent connecting members 3 are connected through telescopic springs 30; thereby, when the dust-facing surface inside the dust bag 1 undergoes contraction deformation (i.e., "sucking"), the surrounding areas can all be subjected to corresponding pulling force, so that it shakes evenly, which is conducive to the falling of dust particles.

[0036] Based on the above embodiment, a limit protection mechanism is further provided between the slider 202 and the inner wall of the sleeve 200. The main purpose of the limit protection mechanism is to limit the adjustment stroke of the threaded adjustment rod 20, and to ensure the adjustment accuracy through the cooperation between the elastic limit rod 2020 and the limit groove 21 during the adjustment process, so as to avoid damage to the threaded adjustment rod 20 due to excessive stroke during adjustment by the operator; and the specific structure of the limit protection mechanism is as follows, please refer to Figure 4:It includes a plurality of elastic limiting rods 2020 arranged around the outer periphery of the slider 202, and limiting grooves 2021 arranged corresponding to the elastic limiting rods 2020 and equidistantly distributed from top to bottom on the inner wall of the sleeve 200. It should be noted that this embodiment only proposes a preferred implementation method for the limiting protection mechanism, and does not specifically limit it. In actual application, other mechanisms such as latches can be selected for replacement according to the installation environment.

[0037] Embodiment 2:

[0038] Based on the above embodiment, it should be noted that the above scheme is that when the dust bag 1 is reversely sucked, its internal dust-facing surface is subjected to the suction wind force, and the interior thereof shakes and deforms, thereby shaking and dropping the dust particles. What needs to be supplemented here is that since the dust bag 1 is connected to the through hole of the partition through an elastic telescopic member, and the spring of the elastic connection member is located at the bottom end of the threaded adjustment rod 20 and connected to the interior of the dust bag 1, during reverse suction, its shaking deformation is only the internal dust-facing surface of the dust bag 1, and for the dust bag 1 as a whole, its shaking force is limited. Therefore, in order to further improve the overall shaking force of the dust bag 1 so that it can thoroughly shake and drop the dust particles inside, a movable member 4 is also provided between the threaded adjustment rod 20 and the hook buckle member, such as Figure 6 and Figure 7 As shown, the movable part 4 includes: a connecting tube 40 and a plug rod 41, the top of the plug rod 41 is fixedly connected to the hook fastener, the connecting tube 40 is hollow inside and open at the top, a blocking ring 42 is provided around the top opening of the connecting tube 40, the bottom end of the plug rod 41 extends into the connecting tube 40, and slides with the connecting tube 40 through an anti-slip head 43, and an elastic hydraulic rod 44 is also provided in the anti-slip head 43. Based on the above structure, when the dust bag 1 is back-sucking and cleaning, that is, when the dust bag 1 is deformed and shaken inside, the dust bag 1 as a whole can also be pulled by the back-sucking wind force, and the movable part 4 can also make the dust bag 1 as a whole shake up and down in a vertical direction, thereby promoting it to shake and drop the dust particles, so as to further improve the dust removal effect.

[0039] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
