Description

Technical Field

[0001] The present invention relates to the technical field of pulse dust removal, and particularly relates to an intelligent pulse dust removal device and a using method thereof. Background Art

[0002] A pulse dust removal device is a device specifically for treating waste gas with a high dust content. The pulse dust removal device mainly consists of a filter bag chamber, an air bag, a gas source supply system and other parts. The pulse dust removal device intercepts the dust (dust) in the waste gas outside through the filtering action of the filter bag, and forms a filter cake on the outer side of the filter bag. Then, when the resistance of the filter bag reaches a certain value, the gas source supply system starts to work, applies a pulse air flow into the filter bag, and thus performs backflushing cleaning on the filter bag to achieve intelligent automatic cleaning.

[0003] During the self-cleaning process of the existing pulse dust removal device, only a pulse air flow (high-pressure air) is simply applied into the filter bag. However, the degree of adhesion of the dust attached to the outer side of the filter bag varies. When the dust with a low adhesion degree is cleaned, the pulse air flow will be discharged from the cleaned area and cannot continuously act on the area where there is still dust residue, resulting in poor cleaning effect, and the number of times of subsequent cleaning of the filter bag will also increase synchronously, thereby reducing the working efficiency of the dust removal device.

The limiting sleeve is provided with a first limiting groove, and the first limiting groove is in limiting cooperation with the first protrusion on the adjacent second moving member. The limiting sleeve is fixedly connected with uniformly arranged one-way plates, and the one-way plates are located in the first limiting groove and are in limiting cooperation with the first protrusion on the second moving member. The limiting sleeve is provided with a second limiting groove, and the second limiting groove is in limiting cooperation with the second protrusion on the adjacent moving sleeve; a plurality of knocking components arranged at intervals and all arranged on the first rod, and the knocking components are used for knocking adjacent filter bags.

[0008] Preferably, the connecting plate is provided with a plurality of holes above adjacent fan blades and adjacent spiral plates for allowing air flow to impact the two.

[0009] Preferably, the spiral plate is an elastic plate, and the first limiting groove is composed of a plurality of first grooves arranged at intervals and a plurality of second grooves arranged at intervals connected to each other. The first grooves and the second grooves are arranged alternately, and the one-way plates are located at the connection between the first grooves and the second grooves.

[0010] Preferably, the upper side of the spiral plate is an inclined surface, and the thickness of the spiral plate near the adjacent first rod is greater than that of the other side, for guiding the air flow so that the air flow blows to the inner side of the filter bag.

[0011] Preferably, the knocking component includes: a third rod fixedly connected to the first rod; a fourth rod fixedly connected to the third rod; a limiting rod fixedly connected to the second rod, the limiting rod being in extrusion fit with the fourth rod, and the fourth rod being in contact fit with the adjacent filter bag.

[0013] Preferably, the elastic coefficient of the third rod is greater than that of the fourth rod to increase the number of times the fourth rod knocks the filter bag.

[0014] Preferably, a usage method of an intelligent pulse dust removal device, based on the above-mentioned intelligent pulse dust removal device, includes the following steps:

[0015] S1: Introduce the waste gas into the lower cavity of the dust removal box. Subsequently, after the waste gas is filtered by the filter bag, it enters the upper cavity of the dust removal box. During this process, the filter bag removes the dust in the waste gas to achieve the purpose of waste gas dust removal, and the clean gas is then discharged from the device through the air outlet pipe;

[0016] S2: After the filter bag becomes blocked, the air bag starts to input high-pressure air into the air supply pipe. The high-pressure air enters the first moving part through the adjacent hose, and then enters the filter bag through the one-way valve to perform backwashing on the filter bag and blow off the dust accumulated on the outer side of the filter bag;

[0017] S3: The high-pressure air impacts the fan blade, causing the second moving part to rotate and move, so that the moving sleeve moves and rotates, thereby making the filter bag have a spiral fold, destroying the aggregation form of the dust adhering to the outer side of the filter bag, and then the filter bag quickly resets under the action of the elastic force of the spiral plate;

[0018] S4: The movement of the second moving part drives the second rod to move together. The limiting rod squeezes the fourth rod, causing the fourth rod to deflect towards the direction close to the first rod, and then using its own elasticity, it continues to deform after the quick reset is completed, so as to knock the adjacent area inside the filter bag.

[0019] Compared with the prior art, the present invention has at least the following advantages: By the relative movement between the movable sleeve and the adjacent limiting sleeve (the movable sleeve drives the adjacent filter bag to move), the shape of the filter bag is changed, causing the filter bag to have wrinkles, promoting the detachment of the dust adhered to its outer side, thereby improving the cleaning effect of the filter bag and the efficiency of subsequent dust removal of the waste gas; By the contact between the first moving member and the connecting plate, the filter bag becomes "airtight" during the backwashing process, preventing the high-pressure air from overflowing from the outlet of the filter bag, resulting in pressure loss and reducing the effect of backwashing the filter bag; By the rapid reset (reverse rotation) of the movable sleeve under the limiting action of the second limiting groove, the "spiral" wrinkles on the filter bag are quickly flattened, and the inertia is used to make the dust adhered to the outer side of the filter bag detach, ensuring the cleaning effect of the filter bag; By the inertia of the fourth rod itself, after its rapid reset, it can continue to deform, thereby knocking on the adjacent area inside the filter bag, shaking off the dust adhered to the outer side of the filter bag, and further improving the cleaning effect of the filter bag; Through the cooperation between the first limiting groove and the one-way plate, the second moving member can only rotate in one direction, that is, the area where the fourth rod knocks on the inside of the filter bag also continuously changes, preventing repeated knocking on the same area inside the filter bag from aggravating stress concentration, resulting in local damage to the filter bag and affecting the normal operation of the waste gas dust removal work.

Detailed implementation manners

[0028] The present invention will be described in detail below with reference to the attached drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative ways for implementation. Moreover, the attached drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0029] As Figures 1-4 As shown, in an embodiment of the present invention, an intelligent pulse dust removal device is proposed to solve the problem that in the process of using the existing pulse dust removal device, the backwashing effect on the filter bag is poor and it is difficult to completely clean the impurities adhering to the outer side of the filter bag. The device includes: chassis 1; dust removal box 2, fixedly connected to the chassis 1, and the dust removal box 2 is provided with an air inlet pipe, an air outlet pipe and a sewage discharge pipe; isolation plate 3, fixedly connected inside the dust removal box 2, and the isolation plate 3 divides the inside of the dust removal box 2 into upper and lower cavities. The upper cavity is communicated with the air outlet pipe, and the lower cavity is communicated with both the air inlet pipe and the sewage discharge pipe; filter bags 4, a plurality of which are arranged at intervals, and one end of each filter bag 4 is fixedly connected to the isolation plate 3; fixing frame 5, fixedly connected inside the dust removal box 2; limit sleeves 6, a plurality of which are arranged at intervals and are all fixedly connected to the fixing frame 5; moving sleeves 7, a plurality of which are arranged at intervals and are respectively slidably connected to adjacent limit sleeves 6, and the moving sleeves 7 are fixedly connected to the other ends of adjacent filter bags 4; a jetting mechanism, arranged on one side of the dust removal box 2 close to the air outlet pipe, for backwashing and cleaning the filter bags 4; power mechanisms, a plurality of which are arranged at intervals and are respectively arranged on adjacent moving sleeves 7, and the power mechanisms are used to make adjacent limit sleeves 6 and adjacent moving sleeves 7 slide relatively.

[0030] In the above solution, the chassis 1 is welded by steel materials such as angle steel to ensure the stability of each component during the dust removal process. The intake pipe on the dust removal box 2 is connected to the external waste gas pipe, and the outlet pipe on the dust removal box 2 is connected to the external pump body to discharge the waste gas (the waste gas after dust removal) in the dust removal box 2 to the outside of the equipment. The sewage discharge pipe on the dust removal box 2 is connected to the external collection box to store the discharged impurities for subsequent unified treatment. When dust removing the waste gas (dust-containing gas, hereinafter referred to as waste gas for convenience of description), the waste gas is introduced into the lower cavity of the dust removal box 2, and then enters the upper cavity of the dust removal box 2 after being filtered by the filter bag 4. During this process, the filter bag 4 removes the dust in the waste gas to achieve the purpose of waste gas dust removal. The clean gas (the waste gas after dust removal) is then discharged from the equipment through the outlet pipe. As the time of treating the waste gas increases, the dust accumulated on the outer side of the filter bag 4 gradually increases. When the dust accumulation affects the normal dust removal work, the dust removal work of the waste gas is stopped, and the filter bag 4 is blown back by the jet mechanism to remove the dust accumulated on the outer side of the filter bag 4, ensuring the permeability of the filter bag 4 and thus ensuring the dust removal efficiency of the waste gas. During the process of blowing back the filter bag 4, the power mechanism is used to make the moving sleeve 7 and the adjacent limiting sleeve 6 move relative to each other (the moving sleeve 7 drives the adjacent filter bag 4 to move), thereby changing the shape of the filter bag 4, causing the filter bag 4 to wrinkle and promoting the detachment of the dust adhering to its outer side, so as to improve the cleaning effect of the filter bag 4 and the dust removal efficiency of the subsequent waste gas.

[0031] As Figures 2-5 shown, the jet mechanism includes: an air bag 801, installed on the upper part of the right side of the dust removal box 2, and the air bag 801 is connected to an external air pump; an air delivery pipe 802, fixedly connected to the upper part inside the dust removal box 2, and the air delivery pipe 802 is communicated with the air bag 801; a plurality of connecting frames 803, which are arranged at intervals and are all fixedly connected to the air delivery pipe 802; a plurality of first moving parts 804, which are arranged at intervals and are respectively slidably connected to the adjacent connecting frames 803. A cavity is provided inside the first moving part 804, and the cavity inside the first moving part 804 is communicated with the air delivery pipe 802 through a flexible hose. An elastic element 805 is fixedly connected between the first moving part 804 and the connecting frame 803. The first moving part 804 is provided with a plurality of one-way valves 806 arranged at intervals, and the one-way valves 806 are communicated with the cavity on the first moving part 804; a plurality of connecting plates 807, which are arranged at intervals and are all rotatably connected to the isolation plate 3, and the first moving part 804 is in contact and cooperation with the connecting plate 807.

[0032] In the above solution, a pressure sensor (not shown in the schematic diagram) is installed in the air outlet pipe on the dust removal box 2 to measure the pressure difference on both sides of the filter bag 4 to detect its resistance change, so as to determine whether it is necessary to clean the filter bag 4. The elastic element 805 is a tension spring used to reset the first moving part 804. The flow direction of the one-way valve 806 is from top to bottom. The hose between the first moving part 804 and the air supply pipe 802 is a corrugated pipe. During the process of dust removal from the waste gas, when the pressure sensor detects a decrease in the pressure at the outlet of the filter bag 4, the air bag 801 starts to input high-pressure air into the air supply pipe 802. The high-pressure air enters the cavity inside the first moving part 804 after passing through the adjacent hose (corrugated pipe). Since the high-pressure air exerts a downward force on the first moving part 804, that is, the first moving part 804 starts to move downward. The first moving part 804 and the connecting frame 803 slide relative to each other, and the elastic element 805 is stretched until the first moving part 804 moves downward to contact the connecting plate 807 (partial areas between the two intersect with each other). Then the high-pressure air exits from the one-way valve 806 and enters the filter bag 4 to perform backwashing on the filter bag 4, blowing off the dust accumulated on the outside of the filter bag 4, and using the contact between the first moving part 804 and the connecting plate 807 to make the filter bag 4 "airtight" during the backwashing process, so as to prevent the high-pressure air from overflowing from the outlet of the filter bag 4, resulting in pressure loss and reducing the effect of backwashing the filter bag 4.

[0033] As Figures 4-7As shown in the figure, the power mechanism includes: a second moving member 901, which is rotationally connected to the adjacent moving sleeve 7 in a limited manner. The second moving member 901 is provided with a first protrusion, and the moving sleeve 7 is provided with a second protrusion; a first rod 902, which is fixedly connected to the adjacent connecting plate 807; a second rod 903, which is fixedly connected to the adjacent second moving member 901. The second rod 903 is splined to the first rod 902. The first rod 902 is fixedly connected with a plurality of fan blades 904 arranged circumferentially; a spiral plate 905, which is fixedly connected between the adjacent connecting plate 807 and the adjacent second moving member 901. The spiral plate 905 is an elastic plate. The upper side of the spiral plate 905 is an inclined surface, and the thickness of the spiral plate 905 on the side close to the adjacent first rod 902 is greater than that on the other side, for guiding the air flow so that the air flow blows to the inner side of the filter bag 4. The limiting sleeve 6 is provided with a first limiting groove 906, and the first limiting groove 906 is in limiting cooperation with the first protrusion on the adjacent second moving member 901. The first limiting groove 906 is composed of a plurality of first grooves 9061 arranged at intervals and a plurality of second grooves 9062 arranged at intervals. The first grooves 9061 and the second grooves 9062 are arranged at intervals. The one-way plate 907 is located at the connection between the first groove 9061 and the second groove 9062. The limiting sleeve 6 is fixedly connected with uniformly arranged one-way plates 907. The one-way plate 907 is located in the first limiting groove 906, and the one-way plate 907 is in limiting cooperation with the first protrusion on the second moving member 901. The limiting sleeve 6 is provided with a second limiting groove 908, and the second limiting groove 908 is in limiting cooperation with the second protrusion on the adjacent moving sleeve 7. The knocking components, which are a plurality of and arranged at intervals, are all arranged on the first rod 902. The knocking components are used to knock the adjacent filter bag 4. The connecting plate 807 is provided with a plurality of holes, and the holes are located above the adjacent fan blades 904 and the adjacent spiral plate 905, for enabling the air flow to impact the two of them.

[0034] In the above solution, the length of the fan blade 904 is greater than the width of the spiral plate 905, and there is a space between the spiral plate 905 and the second rod 903. The upper side of the spiral plate 905 gradually slopes downward from the inside to the outside, that is, the thickness of the inner side of the spiral plate 905 is greater than that of its outer side, for guiding the high-pressure air flow and impacting the inner side of the filter bag 4, thereby improving the backwashing effect on the filter bag 4. The first groove 9061 is an inclined groove, the second groove 9062 is a vertical groove, and the one-way plate 907 is a spring plate, for enabling the second moving member 901 to pass (rotate) unidirectionally. The second limiting groove 908 is an inclined groove. After the high-pressure air enters the filter bag 4, the high-pressure air impacts the fan blade 904, and the fan blade 904 drives the first rod 902 to rotate counterclockwise (as Figure 6Taking the top view direction as an example, the first rod 902 drives the connecting plate 807 and the second rod 903 to rotate counterclockwise together. The connecting plate 807 rotates relative to the isolation plate 3. The second rod 903 drives the second moving member 901 to rotate counterclockwise together. The first protrusion on the second moving member 901 starts to slide along the first groove 9061. Subsequently, under the limiting action of the first groove 9061, the second moving member 901 moves upward while rotating counterclockwise. The spiral plate 905 is compressed. The second moving member 901 drives the moving sleeve 7 to move upward together. The second protrusion on the moving sleeve 7 starts to slide in the second limiting groove 908. Subsequently, under the limiting action of the second limiting groove 908, the moving sleeve 7 rotates counterclockwise while moving upward. The moving sleeve 7 drives the filter bag 4 to move together, causing the filter bag 4 to have "spiral" wrinkles, thereby strengthening the degree of peeling of the dust attached to the outer side of the filter bag 4 and improving the cleaning effect of the filter bag 4.

[0035] When the first protrusion of the second moving member 901 contacts the adjacent one-way plate 907 (the first protrusion moves to the upper end of the first groove 9061), the first protrusion enters the adjacent second groove 9062 after passing through the adjacent one-way plate 907. Subsequently, the second moving member 901 quickly moves downward under the elastic force of the spiral plate 905 (the first protrusion slides downward in the second groove 9062), and the moving sleeve 7 quickly resets (rotates in the reverse direction) under the limiting action of the second limiting groove 908, so that the wrinkles on the filter bag 4 are quickly flattened, and the dust adhered to the outer side of the filter bag 4 is separated by inertia, so as to ensure the cleaning effect of the filter bag 4. After the first protrusion moves downward to contact the adjacent one-way plate 907, the first protrusion enters the first groove 9061 after passing through the one-way plate 907.

[0036] As Figures 5-7 shown, the knocking assembly includes: a third rod 1001, fixedly connected to the first rod 902; a fourth rod 1002, fixedly connected to the third rod 1001. The fourth rod 1002 is inclined. Both the third rod 1001 and the fourth rod 1002 are made of elastic materials and are used to knock the adjacent filter bag 4. The elastic coefficient of the third rod 1001 is greater than that of the fourth rod 1002, which is used to increase the number of times the fourth rod 1002 knocks the filter bag 4; a limiting rod 1003, fixedly connected to the second rod 903. The limiting rod 1003 is in extrusion fit with the adjacent fourth rod 1002, and the fourth rod 1002 is in contact fit with the adjacent filter bag 4.

[0037] In the above solution, multiple fourth rods 1002 are spirally distributed and are used to uniformly strike the filter bag 4. The fourth rods 1002 are inclined downward from top to bottom towards the direction close to the axis of the first rod 902. Both the third rod 1001 and the fourth rod 1002 are made of spring steel. During the upward movement of the second moving member 901, the second moving member 901 drives the second rod 903 to move upward together. The second rod 903 slides relative to the first rod 902. The second rod 903 drives the limiting rod 1003 to move upward together. The limiting rod 1003 begins to squeeze the fourth rod 1002, and the fourth rod 1002 begins to deflect towards the direction close to the first rod 902. The first rod 902 drives the third rod 1001 to deflect together. Then, when the second moving member 901 quickly moves downward to reset, the fourth rod 1002 quickly loses the limit on the fourth rod 1002. The fourth rod 1002 resets under its own inertia and continues to deform after complete reset, thereby striking the adjacent area inside the filter bag 4 to shake off the dust adhered to the outside of the filter bag 4, thereby improving the cleaning effect on the filter bag 4.

[0038] Since the first protrusion on the second moving member 901 can only rotate unidirectionally under the limiting action of the first limiting groove 906, that is, the area where the fourth rod 1002 strikes the inside of the filter bag 4 also continuously changes, so as to prevent repeated strikes on the same area inside the filter bag 4 from aggravating stress concentration, resulting in local damage to the filter bag 4 and affecting the normal progress of the waste gas dust removal work.

[0039] As Figures 1-7 shown, in an embodiment of the present invention, a method for using an intelligent pulse dust removal device is proposed. Based on the above-mentioned intelligent pulse dust removal device, it includes the following steps:

[0040] S1: Introduce the waste gas into the lower cavity inside the dust removal box 2. Subsequently, after the waste gas is filtered by the filter bag 4, it enters the upper cavity inside the dust removal box 2. During this process, the filter bag 4 removes the dust in the waste gas to achieve the purpose of waste gas dust removal, and the clean gas is then discharged from the device through the air outlet pipe.

[0041] S2: After the filter bag 4 becomes blocked, the air bag 801 starts to input high-pressure air into the air supply pipe 802. The high-pressure air enters the first moving member 804 through the adjacent hose, and then enters the filter bag 4 through the one-way valve 806 to perform backwashing on the filter bag 4 and blow off the dust accumulated on the outside of the filter bag 4.

[0042] S3: The high-pressure air impacts the fan blade 904, prompting the second moving member 901 to rotate and move, causing the moving sleeve 7 to move and rotate, so as to make the filter bag 4 have a spiral fold, destroying the aggregation form of the dust adhered to the outside of the filter bag 4, and then the filter bag 4 quickly resets under the elastic force of the spiral plate 905.

[0043] S4: The second moving part 901 moves to drive the second rod 903 to move together. The limiting rod 1003 presses the fourth rod 1002, causing the fourth rod 1002 to deflect towards the first rod 902. Then, using its own elasticity, it continues to deform after the rapid reset is completed, thereby knocking on the adjacent area inside the filter bag 4.

[0044] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without these detailed descriptions. Additionally, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.
