[0002] The device for filtering dust on the market at present, such as a bag filter system, mainly collects dust through the cloth bag covered on the surface of the filter cartridge. After the bag filter system works for a certain period of time, high-pressure gas is used to blow and clean the dust cake on the cloth bag, so that the dust cake falls off and falls into the waste residue tank (powder collecting container). At this time, the dust cake falling into the waste residue tank is in a fluffy state, and there are a large number of cavities in the dust, which will quickly fill the waste residue tank, but it is difficult to achieve the ideal collection amount, the space utilization rate in the waste residue tank is low, and after the waste residue tank is filled with dust, the powder will accumulate in the filter hopper, affecting the filtering efficiency of the filter, therefore, the waste residue tank needs to be cleaned frequently, so as to control the powder accumulation content in the filter. Therefore, the waste residue tank needs to be replaced continuously when the bag filter system is working, which is not conducive to the continuity of production. SUMMARY

[0005] Preferably, the inner wall of the air bag defines a first organically folded part, the outer wall of the air bag defines a second organically folded part, the first organically folded part has a plurality of foldable first wrinkles, the second organically folded part has a plurality of foldable second wrinkles, and the number of the first wrinkles is greater than the number of the second wrinkles.

[0023] Reference Figures 1 to 4As shown, according to the waste residue tank 1 provided by the embodiment of the present application, the waste residue tank 1 includes a waste residue tank body 1 and an air bag 2. The waste residue tank body 1 is in a cylindrical shape. The waste residue tank body 1 is provided with a first mounting port 11 at the top. The top center of the waste residue tank body 1 is connected with a discharge valve 12, which is a straight-through type stop valve. The air bag 2 is provided with an air pipe 21 at the top. The air pipe 21 is vertically upwardly arranged. The air pipe 21 is arranged through the first mounting port 11. The outer circumferential wall of the air pipe 21 and the inner circumferential wall of the first mounting port 11 are in abutment, that is, the air pipe 21 and the first mounting port 11 are in interference fit. At this time, the top of the air bag 2 is fixed. The air bag 2 is a rotary body with a cross section in the shape of a ring (the width of the ring in the cross section is the thickness of the air bag 2 at the corresponding height) and defines a powder passing channel 22. The powder passing channel 22 and the discharge valve 12 are in communication. At this time, the waste residue tank body 1, the discharge valve 12 and the powder passing channel 22 (or the air bag 2 with a rotary body structure) are coaxial. The bottom surface of the air bag 2 defines a pressing surface 23 parallel to the inner bottom surface of the waste residue tank body 1. The air bag 2 is inflated and deflated to drive the pressing surface 23 to move towards or away from the inner bottom surface of the waste residue tank body 1. Specifically, the air bag 2 is connected with an external air source through the air pipe 21. The external air source is connected with an upper computer. The upper computer can control the air source to inflate or deflate the air bag 2 according to a set program (for example, detecting that the dust in the waste residue tank body 1 reaches a certain height, weight, etc.). The air source inflates the air bag 2 to make the air bag 2 expand and drive the pressing surface 23 to move downward, or the air source deflates the air bag 2 to make the air bag 2 contract and drive the pressing surface 23 to move upward. In addition, in the present application, the air bag 2 can be made of wear-resistant materials such as neoprene and nitrile rubber. The pressing surface 23 at the bottom of the air bag 2 is hardened during production to ensure that the pressing surface 23 only moves vertically during inflation and deflation of the air bag 2, and does not deform. In other embodiments, the air pipe 21 and the first mounting port 11 can also be in threaded fit, which will not be described here.

[0024] It can be understood that when the loose dust falls into the waste residue tank body 1 through the discharge valve 12 and accumulates to a certain height, the air bag 2 will be inflated under the control of the upper computer. After inflation, the pressing surface 23 at the bottom of the air bag 2 will move downward towards the inner bottom surface of the waste residue tank body 1, thereby compacting the loose dust in the waste residue tank body 1. Then the air bag 2 is deflated and reset. After resetting, production can continue until the loose dust in the waste residue tank body 1 accumulates to a certain height again. The air bag 2 performs inflation and deflation actions until the waste residue tank body 1 is filled with compacted dust.

[0025] By setting the air bag 2 to compact the powder, not only can the internal cavities of the powder be compressed, delaying the filling time of the waste residue tank body 1 and greatly improving the dust collection efficiency, but also during the deformation process of the air bag 2, there are no mechanical moving parts, which can avoid the dust in the waste residue tank body 1 from contaminating the mechanical moving parts and causing movement failure, effectively prolonging the service life of the waste residue tank body 1 and improving the durability of the waste residue tank body 1. In addition, during the inflation process of the air bag 2, the compaction degree can be adjusted by adjusting the air pressure, which is suitable for various powders of different densities that need to be compacted, effectively improving the practicality of the waste residue tank body 1.

[0026] Referring to Figure 2 and Figure 3 It can be understood that the inner wall of the air bag 2 defines a first concertina folding part 24, and the outer wall of the air bag 2 defines a second concertina folding part 25. The first concertina folding part 24 has a plurality of foldable first folds formed by two conical inner side walls arranged at an angle and connected to each other. The plurality of first folds are connected in sequence along the axial direction of the air bag 2 (the same conical inner side wall is shared by adjacent two first folds). The second concertina folding part 25 has a plurality of foldable second folds formed by two conical outer side walls arranged at an angle and connected to each other. The plurality of second folds are connected in sequence along the axial direction of the air bag 2 (the same conical outer side wall is shared by adjacent two second folds). In the vertical direction, the first folds at both ends of the first concertina folding part 24 are respectively connected to the outer edges at the upper and lower ends of the air bag 2, and the second folds at both ends of the second concertina folding part 25 are respectively connected to the inner edges at the upper and lower ends of the air bag 2. When the air bag 2 is inflated, the angles of the first folds and the second folds increase, and the first concertina folding part 24 and the second concertina folding part 25 are unfolded synchronously, and the pressing surface 23 moves downward. When the air bag 2 is deflated, the angles of the first folds and the second folds decrease, and the first concertina folding part 24 and the second concertina folding part 25 are folded synchronously, and the pressing surface 23 moves upward.

[0027] By setting the first concertina folding part 24 and the second concertina folding part 25 to realize the inflation and expansion of the air bag 2 and the deflation and contraction, on the one hand, the expansion and contraction of the air bag 2 is converted into the folding and unfolding of the first folds and the second folds, which ensures the straight movement of the pressing surface 23 and avoids the problem of inclination and deviation, thereby improving the movement stability of the pressing surface 23. On the other hand, the first concertina folding part 24 and the second concertina folding part 25 have a stacked structure when folded, which can shorten the axial length of the air bag 2, thereby reserving more space between the pressing surface 23 and the inner bottom surface of the waste residue tank body 1, and enhancing the dust handling performance of the waste residue tank body 1.

[0028] Optionally, the number of first folds and the number of second folds can be equal or unequal. In this application, there are nine first folds and three second folds. Setting the density of the first folds on the inner wall of the airbag 2 to be greater than the density of the second folds can provide matching deformation margins for the inner and outer walls of the airbag 2. The numerous and dense first folds on the inner wall control the extension and contraction length of the airbag 2, achieving precise control of the pressure of the airbag 2. The fewer and sparser second folds on the outer wall provide rapid and stable deformation, ensuring a smoother and more uniform overall deformation process of the airbag 2, improving the stability of the movement of the extrusion surface 23. By setting the first and second folds with different shapes, the stress in the inner ring of the airbag 2 is dispersed and the stress distribution in the outer ring is made more uniform, reducing local fatigue damage and improving the structural stability of the airbag 2.

[0029] In some embodiments, the folding points of the first fold (i.e., the connection between the two conical inner sidewalls of the first fold) and the folding points of the second fold (i.e., the connection between the two conical outer sidewalls of the second fold) are both rounded corner structures. The folding points of the first fold and the second fold are the areas where the airbag 2 is subjected to stress-induced stretching or folding deformation during inflation and deflation. The rounded corner structure can absorb the stress during the deformation of the airbag 2, avoid stress concentration leading to local damage, and further extend the service life of the airbag 2.

[0030] Reference Figure 1 and Figure 4 As shown, the waste residue tank body 1 includes a tank body 13 and a cover 14, with the outer peripheral walls of the tank body 13 and the cover 14 being flush. A discharge valve 12 is connected to the cover 14, and a first mounting port 11 is opened on the cover 14. The tank body 13 and the cover 14 are connected by clamps. Specifically, the outer wall of the tank body 13 has an annular first protrusion, and the outer wall of the cover 14 has an annular second protrusion. The first and second protrusions are arranged opposite each other and fixed by a fixing clamp 15.

[0031] The tank body 13 and the cover 14 are connected by a fixing clamp 15, which facilitates the installation and disassembly of the cover 14, thereby facilitating the installation and maintenance of the airbag 2, effectively improving the ease of loading and unloading the airbag 2, and reducing the later maintenance cost of the waste residue tank body 1.

[0032] Furthermore, a first sealing strip 16 is sandwiched between the tank body 13 and the cover body 14. Both sides of the first sealing strip 16 are provided with annular positioning parts. The tank body 13 and the cover body 14 are respectively provided with annular grooves on opposite sides, and the two positioning parts are confined within the annular grooves.

[0033] By setting the first sealing strip 16, when the fixing clamp 15 clamps the tank body 13 and the cover 14, the first sealing strip 16 is deformed by pressure, thereby filling the gap between the tank body 13 and the cover 14, effectively improving the sealing performance of the waste residue tank body 1 and preventing dust leakage.

[0034] Optionally, in some embodiments, the cover 14 and the discharge valve 12 are also clamped and connected, and a second sealing strip is clamped between the cover 14 and the discharge valve 12. The connection between the cover 14 and the discharge valve 12 is specifically described with reference to the foregoing description of the connection between the tank body 13 and the cover 14, and will not be described here again.

[0035] Referring to Figure 1 As shown, it can be understood that the side wall of the tank body 13 is provided with a racetrack-shaped opening, and a transparent observation window 131 is fixed at the opening and is welded or flange-connected to the tank body 13.

[0036] By arranging the observation window 131, the user can not only observe the height of the compacted dust cake in the waste residue tank body 1 in real time, but also observe the use of the air bag 2 and the dust adhesion on the surface of the air bag 2, and timely judge whether the air bag 2 needs to be cleaned and replaced or whether the work needs to be stopped, thereby effectively improving the user experience.

[0037] Referring to Figure 1 As shown, it can be understood that the cover 14 is provided with a second installation opening 141 which can be opened and closed, and the second installation opening 141 is connected with an external water source. Optionally, the second installation opening 141 can be closed by a detachable plug, valve body or cap, and the like, and will not be described here again.

[0038] By arranging the second installation opening 141, when the waste residue tank body 1 is filled with compacted dust, the user can clean the waste residue tank body 1 by water injection through the second installation opening 141. During the water injection and soaking process, since the dust cake is compacted, the water can completely immerse the dust cake, so that it is completely soaked, avoiding the problem that the dust cake is too loose in the waste residue tank body 1, the dust in the waste residue tank body 1 floats on the water surface when the water is injected and soaked, and the problem of explosion after contacting oxygen. The use safety of the waste residue tank body 1 is effectively improved.

[0039] Further, a plurality of second installation openings 141 are arranged along the circumference of the waste residue tank body 1.

[0040] By arranging a plurality of second installation openings 141, if each second installation opening 141 is connected with an external water source, multi-point water injection and soaking can be achieved, and the soaking efficiency of the dust cake is improved. In addition, part of the second installation openings 141 can be connected with an external water source, and the remaining installation openings can be used as backup expansion interfaces, which facilitates the installation of other functional components and improves the expandability of the waste residue tank body 1.

[0041] In some embodiments, the waste residue tank body 1 is provided with a sensor assembly, which can be installed in the second installation port 141 in reserve, and the sensor assembly comprises at least one of a material level sensor, a temperature sensor and a pressure sensor. In this application, the cover body 14 of the waste residue tank body 1 is provided with a material level sensor, a temperature sensor and a pressure sensor through three second installation ports 141 respectively.

[0042] The sensor assembly is installed by using the second installation port 141 in reserve, so that the installation of the sensor assembly does not need to open additional installation structures, and the utilization rate of the structure of the cover body 14 is improved. By installing the material level sensor, the temperature sensor and the pressure sensor, the material level sensor can detect the height of the compacted dust cake in the tank body 13, the temperature sensor can detect the temperature in the tank body 13, and the pressure sensor can detect the pressure in the tank body 13. The material level sensor, the temperature sensor and the pressure sensor can detect the physical parameters in the tank body 13 in real time, so that the host computer can determine the production condition, and the controllability of the waste residue tank body 1 is improved.

[0043] Referring to Figure 2 As shown in FIG. 1, it can be understood that the connection between the air pipe 21 and the top surface of the air bag 2 is provided with a top block 26, and the top block 26 is arranged around the air pipe 21 and abuts against the inner top surface of the waste residue tank body 1.

[0044] By arranging the top block 26, after the air pipe 21 is fixed, the top block 26 abuts against the inner top surface of the waste residue tank body 1 (i.e. the bottom surface of the cover body 14), so that there is a gap between the cover body 14 and the top surface of the air bag 2, which avoids that the air bag 2 blocks the second installation port 141, ensures that the subsequent water can flow smoothly, or ensures that the detection end of the material level sensor, the temperature sensor and the pressure sensor can extend into the tank body 13, and the structural rationality of the air bag 2 is improved.

[0045] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. It is unnecessary and impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
