Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and in particular to a horizontal cloth drum dust collector for a grain workshop based on module assembly and a dust removal method. Background Art

[0002] In the practical dust removal operations of grain storage warehouses, bag dust collectors are mostly used to achieve dust removal purposes. The working principle of bag dust collectors is based on the filtering effect of filter bags on dust. However, during its operation, as dust accumulates on the surface of the filter bags, the ventilation resistance will continue to rise. From the perspective of aerodynamics and the operating mechanism of the dust removal system, in order to ensure that the entire system can maintain sufficient ventilation volume and thus ensure stable and standard dust removal effects, it is necessary to use fans to provide higher wind pressure to overcome the ventilation resistance caused by dust accumulation in the filter bags. However, this measure will inevitably lead to a significant increase in fan energy consumption, disrupting the energy consumption balance of the original dust removal system.

[0003] Especially in the specific operation scenario of the dust removal system of the grain warehouse, if the bag dust collector fails to carry out effective cleaning operations in time after running for a certain period of time, the fan energy consumption will show a more obvious upward trend, which will directly lead to a sharp increase in the electricity cost of the entire grain warehouse, bringing an adverse impact on the operating cost control of the grain warehouse.

[0004] Chinese Patent Publication No. CN105964072B discloses a horizontal flat cloth drum dust collector, comprising a housing, a dust inlet provided on the housing, a fan provided on the housing, a suction chamber connected to the fan suction port of the fan, a dust removal chamber connected to the suction chamber on one side, a gas backflush chamber provided on the other side of the dust removal chamber, and a dust collection chamber provided below the dust removal chamber. The present invention provides multiple multi-duct cage frames within the dust removal chamber, resulting in a large dust removal and filtration area. The gas backflush chamber provided on the side of the dust removal chamber allows high-pressure air to be blown back from a blowpipe into the dust removal chamber for dust removal. The blown airflow has high pressure, stable pulses, and is easy to control. Because the various air chambers do not affect each other, the dust cleaning effect is uniform and rapid. A dust collection chamber provided below the dust removal chamber is capable of collecting dust shaken off from the dust removal chamber.

[0005] During the device's operation, the dust removal function is disabled during the backflush cleaning process. Given the high dust production in the grain workshop's operating environment, using a standby backflush cleaning mode would significantly reduce the efficiency of dust removal. This is because during the standby backflush cleaning period, the dust removal equipment is unable to operate normally to handle the continuous dust generation within the workshop. This causes dust to accumulate and cannot be removed promptly, severely impacting the overall efficiency and quality of dust removal, disrupting the workshop's environmental balance and the continuity of the production process.

[0016] A method for removing dust from a grain workshop using a horizontal cloth drum based on modular assembly, using a horizontal cloth drum dust collector for a grain workshop using modular assembly, includes the following steps:

[0017] Step 1: Start the fan to guide the dusty air from the grain workshop into the filter chamber.

[0020] The present application arranges the cloth tube in a partition assembly. When faced with the need to clean and maintain a single cloth tube or multiple cloth tubes, the corresponding partition assembly will close the external air passage, blocking the normal air passage, and at the same time, open the external dust exhaust slot to build a special airflow path. In this state, because the cloth tube is connected to the clean chamber through the air outlet, the clean air will backflush the inner wall of the cloth tube along the preset reverse path. Under the strong action of the backflush airflow, the dust originally attached to the cloth tube will be separated from the outer surface of the cloth tube under the influence of the airflow and fall into the collection chamber under the action of gravity. The dust pushing assembly connected to the bottom of the collection chamber is then activated, and the dust accumulated in the collection chamber is smoothly pushed to the collection chamber by mechanical pushing, thereby achieving effective collection and cleaning of the dust. It solves the technical problem commonly found in existing dust removal devices, namely, it is difficult to clean the dust accumulated on the cloth tube in a timely and effective manner while ensuring the continuous and efficient dust removal operation. It greatly improves the overall performance and reliability of the dust removal device and optimizes the workflow and effect of the dust removal operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 - Figure 5 As shown, the present application provides a horizontal cloth drum dust collector for a grain workshop based on modular assembly, comprising a casing 1 and a fan 2 arranged on the casing 1; the casing 1 comprises a collecting chamber 11, a filter chamber 12 and a clean chamber 13 arranged in sequence; the filter chamber 12 is connected to the air outlet of the fan 2; a rectangular array of partition components 3 are horizontally arranged in the filter chamber 12 and the collecting chamber 11, and the partition component 3 has a placement cavity extending along its length, a cloth drum 4 is coaxially arranged in the placement cavity, and an air outlet 41 connected to the clean chamber 13 is provided at one end of the cloth drum 4, and a filter is formed between the outer surface of the cloth drum 4 and the inner wall of the placement cavity. A central cavity 314; the portion of the partition component 3 located in the filter cavity 12 is provided with an external air passage slot 312 that connects the central cavity 314 and the filter cavity 12 in a manner that can be cut off; the portion of the partition component 3 located in the collection cavity 11 is provided with an external dust exhaust slot 313 that cuts off the central cavity 314 and the collection cavity 11 in a manner that can be connected; a dust pushing component 5 is provided in the central cavity 314, and the dust pushing component 5 is used to push the dust in the central cavity 314 into the collection cavity 11 through the external dust exhaust slot 313; the casing 1 is also provided with an exhaust port 14 that connects the outside world and the clean cavity 13.

[0036] The housing 1 features a clearly defined functional area in its structural design, with a collection chamber 11, a filter chamber 12, and a clean chamber 13 arranged in a specific order. The filter chamber 12 is in stable communication with the air outlet of the fan 2, ensuring that the airflow output by the fan 2 is smoothly directed into the filter chamber 12.

[0037] In the internal space of the filter chamber 12 and the collection chamber 11, a number of laterally arranged partition components 3 are distributed in a rectangular array. The interior of the partition component 3 extends along its own length to form a specific placement cavity. In each placement cavity, a filter element, a cloth tube 4, is coaxially arranged. One end of the cloth tube 4 is constructed with an air outlet 41 connected to the clean chamber 13, so that the clean air filtered by the cloth tube 4 can smoothly enter the clean chamber 13. At the same time, a centralized cavity 314 is naturally formed between the outer surface of the cloth tube 4 and the inner wall of the placement cavity. The centralized cavity 314 plays an important role in temporarily storing dust in the entire dust removal and cleaning process.

[0038] The structural design of the portion of the partition assembly 3 located within the filter chamber 12 is further refined. An external air passage notch 312 is provided, connecting the central chamber 314 to the filter chamber 12 in a tamper-evident manner, thereby controlling the proper airflow path during normal dust removal operations. Furthermore, an external dust discharge notch 313 is provided in the other portion of the partition assembly 3 located within the collection chamber 11, regulating the passage between the central chamber 314 and the collection chamber 11 by either connecting or tampering with it.

[0039] A dust pushing assembly 5 is specifically provided inside the central chamber 314. The main function of the dust pushing assembly 5 is to precisely push the dust accumulated in the central chamber 314 through the external dust discharge slot 313 into the collection chamber 11 through its mechanical driving capability when dust cleaning is required, thereby achieving effective dust collection and transfer.

[0040] In addition, the structural system of the casing 1 is also provided with an exhaust port 14 connecting the external environment and the clean chamber 13 to ensure that the clean air filtered by the cloth tube 4 can be smoothly discharged to the outside, maintaining the air pressure balance and stable operation inside the entire dust removal system.

[0041] like Figure 6 - Figure 10As shown, the separation assembly 3 includes an air cylinder 32, a discharge cylinder 33, a rotating cylinder 34 and a rotating drive member; the air cylinder 32 is arranged in a horizontal rectangular array in the filter chamber 12, and the external air notches 312 are distributed on the air cylinder 32 along the circumference of the air cylinder 32; the discharge cylinder 33 is arranged horizontally in the collection chamber 11 and is coaxial with the air cylinder 32, and the external dust discharge notches 313 are distributed on the discharge cylinder 33 along the circumference of the discharge cylinder 33; the rotating cylinder 34 horizontally penetrates the filter chamber 12 and the The collecting chamber 11 is coaxially rotatably arranged in the air cylinder 32 and the discharge cylinder 33, and the rotating cylinder 34 is provided with an inner air groove 341 that can overlap with the outer air groove 312 and an inner dust exhaust groove 342 that can overlap with the outer dust exhaust groove 313; a drive mounting chamber 15 is also provided in the casing 1, and the drive mounting chamber 15 is located on the side of the collecting chamber 11 away from the filter chamber 12; the rotating drive member is arranged in the drive mounting chamber 15 and is transmission-connected to the rotating cylinder 34.

[0042] The air cylinders 32 are arranged in a rectangular array, precisely positioned horizontally within the interior of the filter chamber 12. External air notches 312 are evenly distributed around the circumference of the cylinders. During the dust collector's normal filtration phase, these notches 312 serve the crucial function of connecting the central chamber 314 with the filter chamber 12, ensuring that dust-laden airflow flows orderly through the cloth cylinders 4 along a predetermined path for filtration, thereby separating dust from clean air.

[0043] The discharge cylinder 33 is stably positioned transversely within the collection chamber 11 and coaxially with the air passage cylinder 32. External dust discharge slots 313 are distributed around the cylinder, playing a key role in the dust removal process. These slots provide a passage for dust in the collection chamber 314 to flow into the collection chamber 11, allowing for subsequent collection and processing.

[0044] The rotating cylinder 34 is arranged in a manner that horizontally passes through the filter chamber 12 and the collection chamber 11, and is coaxial with the air cylinder 32 and the discharge cylinder 33 and can be flexibly rotated and nested therein. On the surface structure of the rotating cylinder 34, an inner air notch 341 and an inner dust exhaust notch 342 are designed. When the rotating cylinder 34 is at a specific rotation angle, the inner air notch 341 can accurately coincide with the outer air notch 312, at which time an air passage is established between the central chamber 314 and the filter chamber 12, meeting the air flow requirements of normal dust removal operations; and when the rotating cylinder 34 rotates to another specific angle, the inner dust exhaust notch 342 will completely coincide with the outer dust exhaust notch 313, thereby opening up a dust exhaust path for the dust in the central chamber 314 to the collection chamber 11, thereby achieving effective execution of the dust cleaning operation.

[0045] The rotary drive element is mounted within the drive mounting cavity 15 and securely connects to the rotating drum 34 via a specific mechanical transmission structure. Upon receiving the corresponding control instructions, the rotary drive element precisely drives the rotating drum 34 to rotate in a predetermined direction, speed, and angle. This precisely controls the overlap between the inner air passage slot 341 and the outer air passage slot 312, and between the inner dust discharge slot 342 and the outer dust discharge slot 313. This allows for efficient switching and precise control of the dust collector's filtering and cleaning operations, ensuring the stable and reliable operation of the entire horizontal cloth drum dust collector under the complex working conditions of a grain workshop, and ensuring its continued and effective performance of both dust removal and cleaning functions.

[0046] like Figure 11 and Figure 12 As shown, the rotary drive member includes a fixed bracket, a sliding cylinder 352, an annular electromagnet 353 and an elastic reset element 354; the fixed bracket is arranged in the drive mounting cavity 15, one end of the rotating cylinder 34 extends into the fixed bracket to form a driving cylinder 343, and the driving cylinder 343 is provided with arc-shaped notches 3431 distributed along its circumference; the sliding cylinder 352 is arranged in the fixed bracket for transverse sliding and is coaxial with the rotating cylinder 34, and a guide pin 352 extending along its radial direction is provided on the circumferential surface of one end of the sliding cylinder 352. 1. The guide pin 3521 passes through the arc-shaped slot 3431 and slides with it. A sliding magnetic ring 3522 is fixed to the end of the sliding cylinder 352 facing away from the guide pin 3521. The annular electromagnet 353 is arranged in the fixed bracket and is coaxial with the sliding magnetic ring 3522. When the annular electromagnet 353 attracts the sliding magnetic ring 3522 to approach the annular electromagnet 353, the rotating cylinder 34 rotates. The elastic reset element 354 is arranged in the fixed bracket and abuts against the end of the sliding magnetic ring 3522 facing the annular electromagnet 353.

[0047] Within the overall structural layout, the fixed bracket is securely positioned within the drive mounting cavity 15, providing a solid mounting foundation and a stable support framework for the other components of the rotary drive. One end of the rotating cylinder 34 extends into the space defined by the fixed bracket, forming the drive cylinder 343 there. The circumferential surface of the drive cylinder 343 is designed with evenly distributed arcuate notches 3431. These arcuate notches 3431 serve as critical guides and limiting tracks during the coordinated motion of the rotating cylinder 34 and the sliding cylinder 352.

[0048] The sliding cylinder 352 is positioned within the fixed bracket in a transversely sliding manner and maintains a coaxial relationship with the rotating cylinder 34. A guide pin 3521 is provided on the circumference of the sliding cylinder 352, extending radially outward. This guide pin 3521 penetrates the arcuate notch 3431 and forms a sliding fit with the arcuate notch 3431. This structural design ensures that when the sliding cylinder 352 slides axially under the action of a specific driving force, the guide pin 3521 can slide relative to the arcuate notch 3431, thereby converting the linear motion of the sliding cylinder 352 into the rotational motion of the rotating cylinder 34, achieving effective conversion and transmission of motion forms.

[0049] The annular electromagnet 353 is precisely mounted within the fixed bracket and maintains a coaxial relationship with the sliding magnetic ring 3522. When the annular electromagnet 353 is energized and generates a magnetic field, according to the principles of electromagnetism, it exerts an attractive force on the sliding magnetic ring 3522. Under the influence of this attractive force, the sliding magnetic ring 3522 will axially approach the annular electromagnet 353. Due to the sliding fit between the guide pin 3521 and the arc-shaped notch 3431, the axial approach of the sliding magnetic ring 3522 is converted into rotational motion of the rotating cylinder 34, thereby achieving precise drive and control of the rotation of the rotating cylinder 34.

[0050] The elastic reset element 354 is also disposed within the fixed bracket, with one end abutting the side of the sliding magnetic ring 3522 facing the annular electromagnet 353. When the annular electromagnet 353 is not energized or is powered off, the elastic reset element 354, leveraging its own elastic restoring force, can push the sliding magnetic ring 3522 back to its initial position, thereby preparing for the next drive cycle. Simultaneously, when the annular electromagnet 353 is energized and attracts the sliding magnetic ring 3522, the elastic element undergoes corresponding elastic deformation, storing elastic potential energy. When the annular electromagnet 353 is powered off, the elastic element releases this stored elastic potential energy, assisting the sliding magnetic ring 3522 in quickly returning to its initial position. This ensures excellent repeatability and stability of the entire rotary drive system, enabling it to continuously and reliably drive the rotating drum 34 to perform precise rotational motion according to predetermined requirements even in complex operating environments. This effectively regulates the overlap of the slots in the partition assembly 3, ensuring that the filtering and dust cleaning functions of the horizontal cloth drum dust collector are accurately and efficiently achieved.

[0051] like Figure 12As shown, the fixed bracket includes a fixing ring 3511 and a connecting column 3512; the fixing ring 3511 is arranged in the driving mounting cavity 15 and is coaxial with the discharge cylinder 33, and the annular electromagnet 353 is coaxially arranged in the fixing ring 3511; the connecting column 3512 is circumferentially distributed between the inner wall of the driving mounting cavity 15 and the fixing ring 3511 along the direction of the axis of the fixing ring 3511, the end of the connecting column 3512 is fixedly connected to the fixing ring 3511, the connecting column 3512 slides through the sliding magnetic ring 3522, and the elastic reset element 354 is sleeved on the connecting column 3512 and is located between the sliding magnetic ring 3522 and the fixing ring 3511.

[0052] The fixed ring 3511 provides a critical reference for the precise positioning of the entire rotating drive within the dust collector's internal structure. The annular electromagnet 353 is securely mounted coaxially within the predetermined space within the fixed ring 3511. This coaxial arrangement ensures that the magnetic field generated by the annular electromagnet 353 acts evenly and effectively on the coaxial sliding magnetic ring 3522.

[0053] One end of the connecting post 3512 is securely connected to the inner wall of the drive mounting cavity 15, while the other end is firmly bonded to the retaining ring 3511. This creates a stable mechanical support structure between the retaining ring 3511 and the inner wall of the drive mounting cavity 15, effectively ensuring the spatial positional stability and structural strength of the retaining ring 3511. As the connecting post 3512 passes through the sliding magnetic ring 3522, it forms a sliding, interpenetrating fit with the sliding magnetic ring 3522. This design allows the sliding magnetic ring 3522 to slide axially on the connecting post 3512 while precisely limiting and guiding its trajectory.

[0054] The elastic reset element 354 is precisely arranged on the connecting column 3512 in a set form, and its spatial position is located between the sliding magnetic ring 3522 and the fixed ring 3511.

[0055] like Figure 6 、 Figure 10 and Figure 12As shown, the dust pushing assembly 5 includes a transmission cylinder 51, a spiral blade 52, a driving gear ring 53, a driven gear ring 55 and a torque output member; the transmission cylinder 51 is rotatably arranged in the drive mounting chamber 15 and is coaxial with the discharge cylinder 33; the spiral blade 52 is coaxially rotatably arranged in the central cavity 314, one end of the spiral blade 52 extends into the collecting chamber 11, and the spiral blade 52 is provided with a connecting piece 521 distributed along its circumference, the connecting piece 521 extends along the axial direction of the spiral blade 52, and the connecting piece 521 is fixed to the end of the transmission cylinder 51 connection; the driving gear ring 53 is rotatably disposed in the drive mounting cavity 15 and is coaxial with the transmission cylinder 51, and one end of the driving gear ring 53 is provided with tooth grooves distributed along its circumference; the driven gear ring 55 is coaxially fitted and slidably disposed on the outer circumferential surface of the transmission cylinder 51, and the driven gear ring 55 can mesh with the driving gear ring 53, and one end of the driven gear ring 55 is provided with a rotating magnetic ring 551 facing the annular electromagnet 353, and the circumferential surface of the transmission cylinder 51 is also provided with an elastic return element 57 for guiding the driven gear ring 55 away from the tooth groove;

[0056] The torque output member is disposed in the drive mounting cavity 15 and is transmission-connected to the driving gear ring 53 .

[0057] The spiral blade 52 is placed in the internal space of the central cavity 314 in a coaxially rotating manner, and one end of the spiral blade 52 extends to the inside of the collecting cavity 11, thereby constructing a physical channel for pushing dust between the central cavity 314 and the collecting cavity 11 in space. In the structural design of the spiral blade 52, connecting pieces 521 are evenly distributed along its circumference. These connecting pieces 521 extend along the axial direction of the spiral blade 52, and their ends are firmly fixedly connected to the corresponding ends of the transmission cylinder 51. This connection method ensures that after receiving the rotational power, the transmission cylinder 51 can accurately and efficiently transfer the torque to the spiral blade 52, causing the spiral blade 52 to rotate around its own axis. During the rotation of the spiral blade 52, due to its special spiral shape and spatial layout, the dust in the central cavity 314 can be gradually pushed axially to the collecting cavity 11, thereby achieving effective cleaning and transfer of dust.

[0058] One end of the driving gear ring 53 is configured with tooth grooves evenly distributed along its circumference. These tooth grooves serve as key power transmission interfaces during the meshing transmission process between the driving gear ring 53 and the driven gear ring 55 .

[0059] The driven ring gear 55 is cleverly mounted on the outer circumference of the transmission cylinder 51 in a coaxial, sliding manner. Under certain conditions, it can laterally mesh with the teeth of the driving ring gear 53, establishing a power transmission connection between the two. When meshing, the rotation of the driving ring gear 53 is transmitted to the driven ring gear 55 through the intermeshing teeth, thereby driving the transmission cylinder 51 and the spiral blade 52 to rotate.

[0060] One end of the driven gear ring 55 is also provided with a rotating magnetic ring 551 facing the annular electromagnet 353. The rotating magnetic ring 551 can achieve precise control of the position and meshing state of the driven gear ring 55 during the electromagnetic interaction with the annular electromagnet 353. At the same time, an elastic return element 57 is provided on the circumferential surface of the transmission cylinder 51 for guiding the driven gear ring 55 away from the tooth groove. Under normal conditions, the elastic return element 57 maintains the teeth of the driven gear ring 55 in a position disengaged from the tooth groove by its own elastic restoring force to avoid unnecessary power transmission and motion interference. When it is necessary to start the dust pushing assembly 5 for dust cleaning, by controlling the power supply of the annular electromagnet 353 and utilizing the electromagnetic attraction between it and the rotating magnetic ring 551, the driven gear ring 55 overcomes the resistance of the elastic return element 57, achieving meshing of the driven gear ring 55 with the active gear ring 53, thereby starting the power transmission and motion execution process of the entire dust pushing assembly 5.

[0061] The torque output member serves as the power source of the dust pushing assembly 5. It can output a rotational torque of a specific size and direction in a timely manner according to the operation control logic of the dust collector, drive the active gear ring 53 to rotate, and then through the meshing transmission of the active gear ring 53 and the driven gear ring 55, and the connection transmission between the transmission cylinder 51 and the spiral blade 52, finally realize the rotation operation of the spiral blade 52 in the central cavity 314, complete the task of pushing and cleaning the dust in the central cavity 314, and ensure that the horizontal cloth drum dust collector can continuously and efficiently maintain its dust removal and cleaning performance during long-term operation, and adapt to the dust removal operation needs in complex environments such as grain workshops.

[0062] like Figure 12 As shown, a left positioning ring 511 and a right positioning ring 512 are provided on the circumferential surface of the transmission cylinder 51, and the driven gear ring 55 is slidingly provided between the left positioning ring 511 and the right positioning ring 512; the elastic return element 57 is located between the left positioning ring 511 and the driven gear ring 55.

[0063] The sliding range of the driven gear ring 55 can be limited by the left positioning ring 511 and the right positioning ring 512 .

[0064] like Figure 6 and Figure 12 As shown, the torque output member includes a worm 561 and a motor 562. Worm gear teeth are distributed on the outer circumferential surface of the active gear ring 53. The worm 561 is rotatably arranged in the drive mounting cavity 15, and the worm 561 is engaged with the worm gear teeth; the motor 562 is arranged outside the housing 1 and is transmission-connected to the worm 561.

[0065] When the motor 562 is started, the worm 561 can drive the active gear ring 53 to rotate through the worm gear teeth, so that the driven gear ring 55 can transmit torque when meshing with the active gear ring 53 .

[0066] like Figure 3 and Figure 6 As shown, the worm 561 extends along the arrangement direction of the partition components 3 in the same row. The worm 561 can simultaneously drive the rotation of multiple active gear rings 53, and can also drive the rotation of a single active gear ring 53. When it is necessary to activate a single partition component 3, the corresponding driven gear ring 55 is engaged with the corresponding rotating active gear ring 53 to activate the single partition component 3 in the same row. This arrangement allows for targeted cleaning of dusty areas and allows for continued dust removal after the cleaning phase is completed and the filter phase begins.

[0067] like Figure 2 and Figure 3 As shown, the casing 1 also includes a processing bin 16 arranged on the side of the collecting chamber 11, and a discharge port is provided at the bottom of the processing bin 16. A material receiving trough 17 located at the bottom of the discharge cylinder 33 is provided in the collecting chamber 11, and an auger 18 extending into the processing bin 16 is provided in the material receiving trough 17. A synchronous belt 19 is provided between the end of the auger 18 and the end of the worm 561, and the output shaft of the motor 562 is coaxially fixedly connected to the end of the auger 18.

[0068] When the motor 562 is started, the auger 18 rotates in the receiving trough 17 so that the rotating auger 18 pushes the dust in the receiving trough 17 into the processing bin 16 and discharges it outward through the discharge port.

[0069] The synchronous belt 19 can transmit and connect the auger 18 and the worm 561, thereby facilitating the transmission of torque.

[0070] like Figure 8 and Figure 9 As shown, the width direction of the connecting piece 521 deviates from the radial direction of the spiral blade 52.

[0071] In the structural design of the dust-pushing assembly 5, the connecting piece 521 presents a unique layout feature in which its width direction deviates from the radial direction of the spiral blade 52. During the rotation of the spiral blade 52, the connecting piece 521 performs a circular motion. Due to the deviation of the width direction of the connecting piece 521 from the radial direction of the spiral blade 52, the aerodynamic effect generated during its movement has a special mechanism of action. When the connecting piece 521 rotates at high speed, in its specific width direction and spatial posture, it can exert a directional thrust on the air near the outer surface of the cloth tube 4, prompting the air to flow toward the inner wall of the placement cavity. According to the principles of fluid mechanics, this directional flow of air will cause the air pressure in the outer surface area of ​​the cloth tube 4 to decrease, thereby forming a pressure difference environment in which the pressure on the outer surface of the cloth tube 4 is less than the pressure on its inner surface. Driven by this pressure difference, the dust inside the cloth tube 4 will be subjected to a suction force directed to the outer surface of the cloth tube 4, thereby achieving the effect of dust being extracted from the inside of the cloth tube 4.

[0072] At the same time, under the action of the centrifugal force generated by the rotation of the spiral blades 52, the dust drawn to the outer surface of the cloth tube 4 will be thrown toward the inner wall of the placement chamber. From the perspective of mechanical principles, the magnitude of the centrifugal force is proportional to the mass of the dust particles, the rotation radius, and the square of the rotational angular velocity. During the high-speed rotation of the spiral blades 52, the dust particles obtain sufficient centrifugal force to enable them to overcome other forces such as air resistance and stably abut against the inner wall of the placement chamber. In this way, the rotating spiral blades 52 can more effectively interact with the dust abutting against the inner wall of the placement chamber, and with the pushing characteristics of its spiral structure, the dust is gradually pushed along the axial direction of the placement chamber to the collection chamber 11, completing the dust cleaning and transfer process.

[0073] The cloth tube 4 is further provided with a frame 42. A sleeve opening is provided at one end of the cloth tube 4 facing away from the air outlet 41. The cloth tube 4 is sleeved on the frame 42 via the sleeve opening. A sealing disk 43 is provided at the end of the frame 42 near the sleeve opening. The sealing disk 43 is connected to the outer wall of the housing 1. The cloth tube 4 can be removed from the placement cavity through the sealing disk 43, making it easy to replace a new cloth tube 4.

[0074] A method for removing dust using a horizontal cloth drum 4 in a grain workshop based on modular assembly, using a horizontal cloth drum 4 dust collector for a grain workshop based on modular assembly, includes the following steps:

[0075] Step 1: Start the fan 2 to guide the dusty air from the grain workshop into the filter chamber 12. The dusty air passes through the outer air notch 312 and is filtered by the cloth tube 4 before entering the clean chamber 13 through the air outlet 41. The clean air is discharged outward through the exhaust port 14.

[0076] Step 2: Regularly clean the cloth tubes 4 in the same row in the casing 1, start the partition assembly 3 on the outside of the corresponding cloth tube 4, close the external air notch 312 and open the external dust exhaust notch 313, and the gas in the clean chamber backwashes the cloth tube 4 through the air outlet 41, and the backwashed dust passes through the dust pushing assembly 5 and the external dust exhaust notch 313 and falls into the collection chamber 11.

[0077] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
