Description

Technical Field

[0001] The embodiments of the present invention relate to the field of dust removal technology, specifically to a bag filter for building material production. Background Technology

[0002] A bag filter is a dust removal device that separates dust from the air using filter bags. It is widely used in industrial production, especially in industries such as building materials, steel, chemicals, and power. Its main principle is to use the pore structure of the filter bags to filter solid particles in the airflow, thereby purifying gas emissions and meeting environmental protection requirements.

[0003] Patent CN118320538B relates to a bag filter dust collector for building material production. It includes an air inlet seat, a fan fixedly connected to the top of the air inlet seat, an exhaust fan rotatably connected to the side of the fan, a duct fixedly connected to the top of the fan, a housing fixedly connected to the top of the duct, a dust removal component inside the housing for cleaning dust, a mounting seat on the inner top wall of the housing, a central shaft rotatably connected to the bottom of the mounting seat, and an exhaust seat fixedly connected to the top of the opposite side of the housing to the duct. This bag filter dust collector, as described in the patent, uses a spring stretched between an adjusting plate and a horizontal plate. The horizontal plate causes the filter bag to move downwards synchronously. Through the collision between the filter bag and the dust hopper, the dust adhering to the filter bag gradually falls off. Mechanical vibration cleans any residual dust on the outside of the filter bag. The torsional force of the rotating component changes the degree of dust accumulation, achieving the effect of dust settling by gravity.

[0004] In the aforementioned patent, the dust that may remain on the outside of the filter bag is cleaned by mechanical vibration, and the degree of dust accumulation is changed by the torsional force of the rotating parts. However, during long-term operation, the filter bag is prone to gradual blockage of the filter pores, which gradually reduces the dust adsorption effect and affects the dust removal effect and continuous operating efficiency of the equipment. Therefore, a bag dust collector for building material production with better dust removal effect is designed. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a bag filter for building material production, which solves the technical problem in the prior art that the filter bags are prone to gradual clogging of the filter pores during long-term operation, which leads to a gradual decrease in the dust adsorption effect and thus affects the dust removal effect and continuous operating efficiency of the equipment.

[0006] According to one aspect, at least one embodiment of the present invention provides a bag filter for building material production, comprising a main body, a dust removal device for gas dust removal is provided at the bottom of the main body, the dust removal device includes an ash outlet, the ash outlet is fixedly installed at the bottom of the main body, an air inlet pipe is fixedly penetrated through the surface of the ash outlet, an air outlet pipe is fixedly penetrated through the surface of the main body, an air chamber is fixedly installed on the surface of the main body, a blower pipe is fixedly installed on the inner wall of the main body, a circulation fan for controlling the gas flow direction of the main body is provided on the inner wall of the main body, a rotating cylinder is rotatably installed on the inner wall of the main body, a dust removal cylinder is rotatably penetrated through the inner wall of the main body, and an adsorption cylinder is fixedly penetrated through the inner wall of the dust removal cylinder;

[0007] The surface of the adsorption cylinder is fitted with a protrusion 1, the dust removal cylinder is fixedly installed with a telescopic spring rod 1, the free end of the telescopic spring rod 1 is fixedly installed with a protrusion 2, the inner wall of the main body is fixedly installed with a detection cylinder, the inner wall of the detection cylinder is slidably installed with a resistance plate, and the inner wall of the detection cylinder is fixedly installed with a telescopic spring rod 2. The dust removal cylinder is rotated to clean the adsorption cylinder that has not been cleaned, or the adsorption cylinder that needs to be replaced is rotated to one end of the air outlet pipe for replacement by the staff.

[0008] According to the above technical solution, one end of the rotating cylinder is connected to the motor output end, and the rotating cylinder is in contact with the dust collection cylinder. The resistance plate is equipped with a flow rate sensor for sensing instantaneous gas flow rate. The flow rate sensor is equipped with a flow rate sensing module and a signal transmission module. The signal transmission module is electrically connected to the motor connected to the rotating cylinder, so as to avoid equipment downtime due to cleaning and replacement of a single filter material and ensure the continuity of equipment operation.

[0009] According to the above technical solution, the surface of the first protrusion is provided with an arc surface 1 for contacting and striking the surface of the first protrusion, and the surface of the second protrusion is provided with an arc surface 2 for assisting the first protrusion in receiving force. The first protrusion contacts the inner wall of the main body, and the first protrusion drives the adsorption cylinder to vibrate. At this time, the adsorption cylinder is passively cleaned by vibration, which can peel off the fine dust attached deep to the adsorption cylinder and fill the blind spots of high-pressure dust removal.

[0010] According to the above technical solution, the free end of the telescopic spring rod II is fixedly connected to the resistance plate, and the inner wall of the resistance plate is provided with an arc surface III for assisting the gas to receive force. The gas chamber is fixedly connected through the blow pipe. On the other hand, the vibration cleaning force is gentle, avoiding excessive impact of high-pressure gas on the adsorption cylinder and reducing the risk of adsorption cylinder breakage.

[0011] According to another aspect, at least one embodiment of the present invention also provides a bag filter for building material production. The inner wall of the dust collector cylinder is provided with a cleaning device for cleaning the adsorption cylinder. The cleaning device includes a reciprocating screw that rotatably penetrates the surface of the dust collector cylinder. A cleaning disc is slidably installed on the circumferential surface of the adsorption cylinder. A rotating rod is rotatably installed on the inner wall of the main body. A toothed disc is fixedly installed at one end of the reciprocating screw near the rotating rod, and a second toothed disc is fixedly installed at one end of the rotating rod near the reciprocating screw. A cooling pipe is fixedly installed on the surface of the air inlet pipe. A drying tank is rotatably installed on the inner wall of the main body, and a stirring ring is fixedly installed on the inner wall of the drying tank. This increases the contact area between the dried particles and the gas entering through the air inlet pipe, achieving gas drying treatment and preventing moisture in the building material production gas from causing dust to clump on the surface of the adsorption cylinder. This reduces the difficulty of subsequent dust cleaning and prevents clumped dust from clogging the pores of the adsorption cylinder.

[0012] According to the above technical solution, the cleaning disc is slidably connected to the reciprocating screw, and the reciprocating screw is connected to the cleaning disc by a thread. The end of the cooling pipe away from the air inlet pipe is connected to the drying tank. The drying tank is equipped with drying particles for drying the gas. The cleaning disc moves to clean the surface of the adsorption cylinder, avoids the adsorption cylinder, and removes the loose dust initially attached to the surface of the adsorption cylinder.

[0013] According to the above technical solution, one end of the rotating rod is connected to the output end of the motor, the second gear plate meshes with the first gear plate, and a transmission belt is connected between the rotating rod and the drying tank to reduce the workload of subsequent high-pressure cleaning and vibration cleaning.

[0014] According to another aspect, at least one embodiment of the present invention also provides a bag filter for building material production. The surface of the ash outlet is provided with an anti-accumulation device for preventing dust accumulation at the ash outlet. The anti-accumulation device includes a fixing plate, which is fixedly installed on the surface of the ash outlet. A circular rotating rod rotatably passes through the surface of the fixing plate. A contact wheel is fixedly installed on the circumferential surface of the circular rotating rod. A cleaning roller is fixedly installed on the circumferential surface of the rotating rod. A collar is slidably installed on the circumferential surface of the drying tank. A linkage rod is rotatably installed on the circumferential surface of the collar. An anti-accumulation plate is slidably installed on the surface of the ash outlet. A connecting scraper is fixedly installed on the surface of the anti-accumulation plate. The rotation of the cleaning roller drives the brush bristles to rotate, cleaning impurities adhering to or sticking to the inner wall of the dust collector.

[0015] According to the above technical solution, the contact wheel is in contact with the dust removal cylinder, and the circumferential surface of the cleaning roller is provided with bristles for cleaning the inner wall of the dust removal cylinder, so as to avoid long-term accumulation of dust causing corrosion or shedding and contamination of the filtered gas.

[0016] According to the above technical solution, the circumferential surface of the drying tank is provided with a reciprocating threaded groove, the collar is threadedly connected to the drying tank, and the end of the linkage rod away from the collar is rotatably connected to the anti-accumulation plate, thereby realizing full coverage cleaning of the inner wall of the ash outlet, further improving the cleaning effect of the inner wall of the ash outlet, and thus providing smooth ash discharge and smooth equipment operation.

[0017] The beneficial effects of the embodiments of the present invention are as follows:

[0018] In this invention, the rotating cylinder rotates under the action of the motor output end. Because the rotating cylinder is in contact with the dust collection cylinder, the rotation of the rotating cylinder drives the dust collection cylinder to rotate. At this time, the rotation of the dust collection cylinder cleans the adsorption cylinder that has not been cleaned, or rotates the adsorption cylinder that needs to be replaced to one end of the air outlet pipe for replacement by the staff. This avoids equipment downtime due to cleaning and replacement of a single filter material and ensures the continuity of the storage operation.

[0019] In this invention, protrusion two rotates and contacts and strikes the surface of protrusion one. At this time, protrusion one drives the adsorption cylinder to vibrate. The adsorption cylinder is passively cleaned by vibration, which can remove fine dust adhering deep to the adsorption cylinder and fill the blind spots of high-pressure cleaning. On the other hand, the vibration cleaning force is gentle, avoiding excessive impact of high-pressure gas on the adsorption cylinder and reducing the risk of adsorption cylinder damage. The flow rate sensor transmits the signal to the rotating cylinder through the signal sensing module. At this time, the rotating cylinder drives the dust collection cylinder to rotate adaptively as the gas flow increases or decreases, adjusting the frequency of passive cleaning of the adsorption cylinder, avoiding energy waste caused by over-cleaning, and preventing adsorption cylinder blockage caused by insufficient cleaning, thus achieving a balance between energy consumption and dust removal effect.

[0020] In this invention, the rotation of the drying tank drives the rotation of the stirring ring, which in turn stirs the drying particles inside the drying tank. This increases the contact area between the drying particles and the gas entering through the inlet pipe, thus achieving gas drying. This prevents the moisture in the building material production gas from causing dust to clump on the surface of the adsorption cylinder, reducing the difficulty of subsequent dust removal and preventing clumped dust from clogging the pores of the adsorption cylinder.

[0021] In this invention, the rotation of the gear disc drives the rotation of the reciprocating screw. Since the reciprocating screw is connected to the cleaning disc by a thread, the rotation of the reciprocating screw drives the cleaning disc to move. At this time, the cleaning disc moves to clean the surface of the adsorption cylinder, avoids the adsorption cylinder, removes the loose dust initially attached to the surface of the adsorption cylinder, and reduces the workload of subsequent high-pressure cleaning and vibration cleaning.

[0022] In this invention, the contact wheel rotates, driving the circular rotating rod to rotate, which in turn drives the cleaning roller to rotate. The rotating cleaning roller, in turn, drives the brush bristles to clean impurities adhering to or sticking to the inner wall of the dust collector, preventing long-term accumulation of ash from causing corrosion or detachment and contaminating the filtered gas. The movement of the anti-accumulation plate's movable parts causes the connecting scraper's fixing parts to move, allowing the connecting scraper to simultaneously clean the inner wall. This achieves full coverage cleaning of the ash outlet's inner wall, further improving the cleaning effect and thus enhancing the smoothness of ash discharge and the equipment's operation.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0035] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0039] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] like Figures 1-9 As shown, this invention illustrates a baghouse dust collector for building material production according to an embodiment of the present invention. It includes a main body 1, with a dust collector at the bottom of the main body 1 for gas dust removal. The dust collector includes an ash outlet 21, which is fixedly installed at the bottom of the main body 1. An air inlet pipe 22 is fixedly passed through the surface of the ash outlet 21. An air outlet pipe 23 is fixedly passed through the surface of the main body 1. An air chamber 24 is fixedly installed on the surface of the main body 1. A blowpipe 25 is fixedly installed on the inner wall of the main body 1. A circulating fan 26 is provided on the inner wall of the main body 1 to facilitate control of the gas flow direction. A rotating cylinder 27 is rotatably installed on the inner wall of the main body 1. A dust collector cylinder 28 rotatably passes through the inner wall of the main body 1. An adsorption cylinder 29 is fixedly passed through the inner wall of the dust collector cylinder 28.

[0041] The surface of the adsorption cylinder 29 is fitted with a protrusion 31. The dust removal cylinder 28 is fixedly installed with a telescopic spring rod 32. The free end of the telescopic spring rod 32 is fixedly installed with a protrusion 33. The inner wall of the main body 1 is fixedly installed with a detection cylinder 34. The inner wall of the detection cylinder 34 is slidably installed with a resistance plate 35. The inner wall of the detection cylinder 34 is fixedly installed with a telescopic spring rod 36. When the gas moves upward through the adsorption cylinder 29 and impacts the resistance plate 35, the resistance plate 35 moves upward under the action of the gas. At this time, the resistance plate 35 senses the change in gas flow rate through the flow rate sensor set inside it.

[0042] One end of the rotating cylinder 27 is connected to the output end of the motor. The rotating cylinder 27 is in contact with the dust collection cylinder 28. The resistance disk 35 is equipped with a flow rate sensor for sensing the instantaneous gas flow rate. The flow rate sensor is equipped with a flow rate sensing module and a signal transmission module. The signal transmission module is electrically connected to the motor connected to the rotating cylinder 27. The rotating cylinder 27 rotates under the action of the motor output end. The rotating cylinder 27 is in contact with the dust collection cylinder 28.

[0043] The surface of protrusion 31 is provided with an arc surface 1 for contacting and striking the surface of protrusion 31, and the surface of protrusion 33 is provided with an arc surface 2 for assisting protrusion 31 in receiving force. Protrusion 31 contacts the inner wall of the main body 1. At this time, protrusion 33 rotates to contact and strike the surface of protrusion 31. At this time, protrusion 31 drives the adsorption cylinder 29 to vibrate.

[0044] The free end of the telescopic spring rod 36 is fixedly connected to the resistance plate 35. The inner wall of the resistance plate 35 is provided with an arc surface 3 for assisting the gas to receive force. The gas chamber 24 is fixedly connected through the blow pipe 25. When the gas chamber 24 is activated, the gas chamber 24 delivers high-pressure gas to the blow pipe 25. Then the blow pipe 25 sprays high-pressure gas to the adsorption cylinder 29, and the gas flows through one end of the adsorption cylinder 29.

[0045] In this example, gas enters the interior of the dust collector 28 through the inlet pipe 22, and then enters the dust collector 28. At this time, the adsorption cylinder 29 inside the dust collector 28 removes dust from the gas. Simultaneously, the circulation fan 26 is activated, guiding the gas towards the outlet pipe 23. When the adsorption cylinder 29 experiences surface dust accumulation during prolonged operation, affecting its dust removal efficiency, the air chamber 24 is activated. The air chamber 24 delivers high-pressure gas to the blowpipe 25, which then sprays the high-pressure gas onto the adsorption cylinder 29, allowing it to circulate through one end of the adsorption cylinder 29. This achieves... For cleaning the adsorption cylinder 29, when the other two adsorption cylinders 29 need to be cleaned or when the cycle service life of the adsorption cylinder 29 reaches its limit, the rotating cylinder 27 rotates under the action of the motor output. Because the rotating cylinder 27 is in contact with the dust collection cylinder 28, the rotation of the rotating cylinder 27 drives the dust collection cylinder 28 to rotate. At this time, the rotation of the dust collection cylinder 28 will clean the adsorption cylinder 29 that has not been cleaned, or rotate the adsorption cylinder 29 that needs to be replaced to one end of the air outlet pipe 23 for replacement by the staff. This avoids equipment downtime due to cleaning and replacement of a single filter material and ensures the continuity of the collection and operation.

[0046] During normal operation, the rotating cylinder 27 drives the dust collection cylinder 28 to rotate, which in turn drives the telescopic spring rod 32 to rotate. The telescopic spring rod 32 then drives the protrusion 33 to rotate. At this time, the protrusion 33 rotates and contacts and strikes the surface of the protrusion 31. The protrusion 31 then drives the adsorption cylinder 29 to vibrate. This vibration of the adsorption cylinder 29 achieves passive cleaning, which can peel off the fine dust deeply attached to the adsorption cylinder 29 and fill the blind spots of high-pressure cleaning. On the other hand, the vibration cleaning force is gentle, avoiding excessive impact of high-pressure gas on the adsorption cylinder 29 and reducing the risk of damage to the adsorption cylinder 29.

[0047] When the gas moves upward through the adsorption cylinder 29 and impacts the resistance plate 35, the resistance plate 35 moves upward under the action of the gas. At this time, the flow rate sensor inside the resistance plate 35 senses the change in gas flow rate. Since the signal transmission module is electrically connected to the motor connected to the rotating cylinder 27, the flow rate sensor transmits the signal to the rotating cylinder 27 through the signal sensing module. At this time, the rotating cylinder 27 drives the dust collection cylinder 28 to rotate adaptively as the gas flow rate increases or decreases, adjusting the frequency of passive cleaning of the adsorption cylinder 29, avoiding energy waste caused by excessive dust cleaning, and preventing the adsorption cylinder 29 from clogging due to insufficient dust cleaning, thus achieving a balance between energy consumption and dust removal effect. Subsequently, the gas after dust removal by the equipment is discharged through the exhaust pipe 23, and the cleaned dust falls through the dust outlet 21.

[0048] like Figures 1-9 As shown, in another embodiment of the present invention, the inner wall of the dust collector 28 is provided with a cleaning device for cleaning the adsorption cylinder 29. The cleaning device includes a reciprocating screw 41, which rotatably passes through the surface of the dust collector 28. A cleaning disc 42 is slidably installed on the circumferential surface of the adsorption cylinder 29. A rotating rod 43 is rotatably installed on the inner wall of the main body 1. A toothed disc 44 is fixedly installed at one end of the reciprocating screw 41 near the rotating rod 43. A toothed disc 45 is fixedly installed at one end of the rotating rod 43 near the reciprocating screw 41. A cooling pipe 46 is fixedly installed on the surface of the air inlet pipe 22. A drying tank 47 is rotatably installed on the inner wall of the main body 1. An agitator ring 48 is fixedly installed on the inner wall of the drying tank 47. A transmission belt rotates to drive the drying tank 47 to rotate. At this time, the rotation of the drying tank 47 drives the agitator ring 48 to rotate. The rotation of the agitator ring 48 drives the dry particles inside the drying tank 47 to be agitated.

[0049] The cleaning disc 42 is slidably connected to the reciprocating screw 41, and the reciprocating screw 41 is threadedly connected to the cleaning disc 42. The end of the cooling pipe 46 away from the air inlet pipe 22 is connected to the drying tank 47. The drying tank 47 is equipped with drying particles for drying the gas. The rotating stirring ring 48 drives the drying particles inside the drying tank 47 to be stirred, which increases the contact area between the drying particles and the gas entering through the air inlet pipe 22.

[0050] One end of the rotating rod 43 is connected to the motor output end, the second gear 45 meshes with the first gear 44, and the rotating rod 43 is connected to the drying tank 47 by a transmission belt. The rotation of the rotating rod 43 drives the first transmission belt to rotate, and the rotation of the first transmission belt drives the drying tank 47 to rotate.

[0051] In this example, when the rotating rod 43 rotates under the action of the motor output, the drying tank 47 rotates, which drives the stirring ring 48 to rotate. The rotation of the stirring ring 48 drives the drying particles inside the drying tank 47 to be stirred, which increases the contact area between the drying particles and the gas entering through the air inlet pipe 22, thereby achieving the drying treatment of the gas. This prevents the moisture in the building material production gas from causing dust to clump on the surface of the adsorption cylinder 29, which reduces the difficulty of subsequent dust removal and prevents the clumped dust from clogging the pores of the adsorption cylinder 29.

[0052] Simultaneously, the rotation of the rotating rod 43 drives the second gear disk 45 to rotate. Because the second gear disk 45 meshes with the first gear disk 44, the rotation of the second gear disk 45 drives the first gear disk 44 to rotate. The rotation of the first gear disk 44 drives the reciprocating screw 41 to rotate. Because the reciprocating screw 41 is connected to the cleaning disk 42 by a thread, the rotation of the reciprocating screw 41 drives the cleaning disk 42 to move. At this time, the movement of the cleaning disk 42 cleans the surface of the adsorption cylinder 29, avoids the adsorption cylinder 29, removes the loose dust initially attached to the surface of the adsorption cylinder 29, and reduces the workload of subsequent high-pressure cleaning and vibration cleaning.

[0053] like Figures 1-9 As shown, in another embodiment of the present invention, the surface of the ash outlet 21 is provided with an anti-accumulation device for preventing dust accumulation in the ash outlet 21. The anti-accumulation device includes a fixing plate 51, which is fixedly installed on the surface of the ash outlet 21. A circular rotating rod 52 is rotatably installed through the surface of the fixing plate 51. A contact wheel 53 is fixedly installed on the circumferential surface of the circular rotating rod 52. A cleaning roller 54 is fixedly installed on the circumferential surface of the circular rotating rod 52. A collar 55 is slidably installed on the circumferential surface of the drying tank 47. A linkage rod 56 is rotatably installed on the circumferential surface of the collar 55. An anti-accumulation plate 57 is slidably installed on the surface of the ash outlet 21. A connecting scraper 58 is fixedly installed on the surface of the anti-accumulation plate 57. The movement of the movable part of the anti-accumulation plate 57 drives the fixed part of the connecting scraper 58 to move. At this time, the inner wall is cleaned simultaneously by the connecting scraper 58.

[0054] The contact wheel 53 contacts the dust collection cylinder 28. The circumferential surface of the cleaning roller 54 is provided with bristles for cleaning the inner wall of the dust collection cylinder 28. The rotation of the contact wheel 53 drives the circular rotating rod 52 to rotate, and the rotation of the circular rotating rod 52 drives the cleaning roller 54 to rotate.

[0055] The circumferential surface of the drying tank 47 is provided with a reciprocating threaded groove. The collar 55 is threadedly connected to the drying tank 47. The end of the linkage rod 56 away from the collar 55 is rotatably connected to the anti-accumulation plate 57. The movement of the collar 55 drives the linkage rod 56 to rotate. At this time, the rotation of the linkage rod 56 drives the anti-accumulation plate 57 to move obliquely upward to clean the dust on the inner wall of the ash outlet 21.

[0056] In this example, when the cleaning disc 42 moves up and down under the action of the reciprocating screw 41, the movement of the cleaning disc 42 drives the circular rotating rod 52 to move, and the movement of the circular rotating rod 52 drives the contact wheel 53 to move. Because the contact wheel 53 is in contact with the inner wall of the dust collector 28, the contact wheel 53 rotates under the action of the inner wall of the dust collector 28. At this time, the rotation of the contact wheel 53 drives the circular rotating rod 52 to rotate, and the rotation of the circular rotating rod 52 drives the cleaning roller 54 to rotate. At this time, the rotation of the cleaning roller 54 drives the bristles to rotate to clean the impurities attached or stuck to the inner wall of the dust collector 28, so as to avoid long-term accumulation of dust that will cause corrosion or fall off and contaminate the filtered gas.

[0057] Meanwhile, because the collar 55 and the drying tank 47 are connected by threads, the rotation of the drying tank 47 drives the collar 55 to move, and the movement of the collar 55 drives the linkage rod 56 to rotate. At this time, the rotation of the linkage rod 56 drives the anti-accumulation plate 57 to move obliquely upward to clean the dust on the inner wall of the ash outlet 21. At the same time, the movement of the movable part of the anti-accumulation plate 57 drives the movement of the fixed part of the connecting scraper 58. At this time, the inner wall is cleaned simultaneously through the connecting scraper 58. This achieves full coverage cleaning of the inner wall of the ash outlet 21, further improving the cleaning effect of the inner wall of the ash outlet 21, thereby improving the smoothness of ash discharge and the smoothness of equipment operation.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
