Abstract
Description
Technical Field
[0001] The 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 dust removal practice of grain storage warehouses, bag dust collectors are mostly used to achieve the purpose of dust removal. The working principle of bag dust collectors is based on the filtering effect of filter bags on dust. However, during its operation, with the continuous accumulation of dust 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 and thus ensure a stable and up-to-standard dust removal effect, 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, breaking 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 adverse effects on the operation cost control of the grain warehouse.
[0004] Chinese patent announcement number CN105964072B discloses a horizontal flat cloth drum dust collector, including a casing, a dust inlet arranged on the casing, a fan arranged on the casing, 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 arranged on the other side of the dust removal chamber, and a dust collection chamber arranged below the dust removal chamber. The present invention arranges a plurality of multi-duct cage frames in the dust removal chamber, with a large dust removal and filtration area. In the gas backflush chamber arranged on the side of the dust removal chamber, the high-pressure airflow is backflushed from the spray pipe into the dust removal chamber for dust cleaning. The spray airflow pressure is large and the pulse is stable, and the control is convenient. Since the wind chambers do not affect each other, the dust cleaning effect is uniform and fast. A dust collection chamber is arranged below the dust removal chamber, and the dust sprayed and shaken off in the dust removal chamber can be collected.
[0005] In the operation process of the device, when the backflush cleaning procedure is executed, the dust removal function is unavailable. Given that the working environment of the grain workshop is characterized by a large amount of dust generation, if the backflush cleaning operation mode is adopted in the standby state, the efficiency of the dust removal operation will be greatly reduced. This is because during the standby backflush cleaning period, the dust removal equipment cannot operate normally to handle the dust continuously generated in the workshop, causing dust to accumulate in the workshop and cannot be removed in time, which seriously affects the efficiency and quality of the overall dust removal work, and destroys the environmental balance in the workshop and the continuity of the production process.

[0016] A horizontal cloth drum dust removal method for a grain workshop based on modular assembly, using a horizontal cloth drum dust collector for a grain workshop assembled in a modular manner, includes the following steps:
[0017] Step 1: Start the fan to guide the dusty air in the grain workshop into the filter chamber.

The clean air is discharged outward through the exhaust port.
[0018] Step 2: Regularly clean the cloth cylinders in the same row in the casing, start the partition assembly on the outside of the corresponding cloth cylinder, close the external air inlet and open the external dust outlet, and the gas in the clean chamber backwashes the cloth cylinder through the air outlet.

[0020] The present application is achieved by arranging the cloth tube in the partition component. When faced with the need to clean and maintain a single cloth tube or multiple cloth tubes, the corresponding partition component will close the external air passage, block 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 entrainment of the airflow, and fall into the concentrated cavity under the action of gravity. The dust pushing component connected to the bottom of the concentrated cavity is then started, and the dust accumulated in the concentrated cavity is smoothly pushed to the collection cavity by mechanical pushing, thereby realizing the effective collection and cleaning of dust.

DETAILED DESCRIPTION
[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[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 filtering chamber 12 and a clean chamber 13 arranged in sequence; the filtering chamber 12 is connected to the air outlet of the fan 2; a rectangular array of partition components 3 are transversely arranged in the filtering chamber 12 and the collecting chamber 11, and the partition component 3 has a placement chamber extending along its length direction, a cloth drum 4 is coaxially arranged in the placement chamber, and an air outlet 41 connected to the clean chamber 13 is arranged at one end of the cloth drum 4, and a gas outlet 41 connected to the clean chamber 13 is formed between the outer surface of the cloth drum 4 and the inner wall of the placement chamber. 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 connecting the central cavity 314 and the filter cavity 12 in a manner that allows them to be cut off; the portion of the partition component 3 located in the collection cavity 11 is provided with an external dust discharge slot 313 that cuts off the central cavity 314 and the collection cavity 11 in a manner that allows them to 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 discharge slot 313; the casing 1 is also provided with an exhaust port 14 connecting the outside and the clean cavity 13.
[0036] The housing 1 has a clear functional division in structural design, and is provided with a collection chamber 11, a filter chamber 12 and a clean chamber 13 in a specific order. The filter chamber 12 establishes a stable connection with the air outlet of the fan 2, thereby ensuring that the airflow output by the fan 2 can be smoothly introduced 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 direction to form a specific placement chamber. In each placement chamber, a filter element, a cloth tube 4, is coaxially arranged. One end of the cloth tube 4 is configured 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 chamber 314 is naturally formed between the outer surface of the cloth tube 4 and the inner wall of the placement chamber. The centralized chamber 314 plays an important role in temporarily storing dust in the entire dust removal and cleaning process.
[0038] The structural design of the part of the partition component 3 located in the filter chamber 12 is further refined. An external air passage notch 312 is provided, which can connect the central chamber 314 with the filter chamber 12 in a truncation manner, so as to control the reasonable flow path of the airflow during normal dust removal operation; and an external dust discharge notch 313 is provided in the other part of the partition component 3 located in the collection chamber 11, which can regulate the passage between the central chamber 314 and the collection chamber 11 in a truncation or truncation manner.
[0039] A dust pushing assembly 5 is specially provided inside the central cavity 314. The main function of the dust pushing assembly 5 is to accurately push the dust accumulated in the central cavity 314 into the collection cavity 11 through the external dust discharge slot 313 by means of its mechanical driving capability when dust cleaning operation is required, thereby realizing 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 - Fig.10As shown, the partition 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 passing cylinder 32 and the discharge cylinder 33, and the rotating cylinder 34 is provided with an inner air passing slot 341 which can overlap with the outer air passing slot 312 and an inner dust exhaust slot 342 which can overlap with the outer dust exhaust slot 313; a driving installation chamber 15 is also provided in the casing 1, and the driving installation chamber 15 is located on the side of the collecting chamber 11 away from the filtering chamber 12; the rotating driving member is arranged in the driving installation chamber 15 and is transmission-connected to the rotating cylinder 34.
[0042] The air cylinder 32 is in the form of a rectangular array in the overall layout, and is precisely arranged in a horizontal posture in the internal space of the filter cavity 12. The outer air notches 312 are evenly distributed in the circumferential direction. The outer air notches 312 have the important responsibility of connecting the central cavity 314 and the filter cavity 12 during the filtering stage of the normal operation of the dust collector, ensuring that the dust-laden airflow can be filtered and processed in an orderly manner through the cloth cylinder 4 according to the predetermined flow path, thereby realizing the separation of dust and clean air.
[0043] The discharge cylinder 33 is stably arranged in the collection chamber 11 in a transverse manner and maintains a coaxial relationship with the air cylinder 32. The outer dust discharge slots 313 are distributed around it, which play a key role in the dust cleaning process and can provide a passage for the dust in the concentration chamber 314 to the collection chamber 11, so as to collect and process the dust in a centralized manner.
[0044] The rotating cylinder 34 is arranged in a manner of horizontally penetrating 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 passage slot 341 and an inner dust exhaust slot 342 are designed. When the rotating cylinder 34 is at a specific rotation angle, the inner air passage slot 341 can accurately coincide with the outer air passage slot 312, and at this time, an air passage channel is established between the central chamber 314 and the filter chamber 12 to meet the air flow requirements of normal dust removal operations; and when the rotating cylinder 34 rotates to another specific angle, the inner dust exhaust slot 342 will completely coincide with the outer dust exhaust slot 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 member is installed in the drive installation cavity 15, and realizes reliable transmission connection with the rotating drum 34 through a specific mechanical transmission structure. After receiving the corresponding control command, the rotary drive member can accurately drive the rotating drum 34 to rotate according to the predetermined direction, speed and angle, so as to accurately adjust the overlap state between the inner air-through slot 341 and the outer air-through slot 312, and the inner dust-discharging slot 342 and the outer dust-discharging slot 313, so as to realize efficient switching and precise control of the dust collector filtering and cleaning operations, and ensure that the entire horizontal cloth drum dust collector can operate stably and reliably under the complex working conditions of the grain workshop, and continuously and effectively play the dual functions of dust removal and cleaning.
[0046] like Fig.11 and Fig.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 installation 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 transversely slidably arranged in the fixed bracket 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 slidably cooperates with it. A sliding magnetic ring 3522 is fixed to one end of the sliding cylinder 352 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 one end of the sliding magnetic ring 3522 facing the annular electromagnet 353.
[0047] The fixed bracket is firmly arranged at a specific position inside the drive installation cavity 15 in the overall structural layout, providing a solid installation foundation and a stable support frame for other components of the rotating drive. One end of the rotating cylinder 34 extends into the space defined by the fixed bracket, and a driving cylinder 343 structure is formed there. The circumferential surface of the driving cylinder 343 is designed with arc-shaped notches 3431 evenly distributed along its circumference, and the arc-shaped notches 3431 act as a key motion guide and limiting track during the coordinated movement of the rotating cylinder 34 and the sliding cylinder 352.
[0048] The sliding cylinder 352 is placed in the fixed bracket in a transverse sliding manner and maintains a coaxial relationship with the rotating cylinder 34. On the circumferential surface of the sliding cylinder 352, a guide pin 3521 is provided, which extends radially outward. The guide pin 3521 passes through the arc-shaped slot 3431 and forms a sliding fit relationship with the arc-shaped slot 3431. This structural design enables the guide pin 3521 to slide relatively along the track of the arc-shaped slot 3431 when the sliding cylinder 352 slides in the axial direction under the action of a specific driving force, thereby converting the linear motion of the sliding cylinder 352 into the rotational motion of the rotating cylinder 34, thereby realizing the effective conversion and transmission of the motion form.
[0049] The annular electromagnet 353 is precisely mounted inside 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, it will generate an attractive force on the sliding magnetic ring 3522 according to the electromagnetic principle. Under the action of this attractive force, the sliding magnetic ring 3522 will approach the annular electromagnet 353 along the axial direction. Due to the sliding matching relationship between the guide pin 3521 and the arc-shaped notch 3431, the axial approaching movement of the sliding magnetic ring 3522 will be converted into the rotational movement of the rotating cylinder 34, thereby realizing the precise driving and control of the rotation of the rotating cylinder 34.
[0050] The elastic reset element 354 is also arranged inside the fixed bracket, and one end of the elastic reset element 354 abuts against the side of the sliding magnetic ring 3522 facing the annular electromagnet 353. When the annular electromagnet 353 is not powered on or powered off, the elastic reset element 354 can push the sliding magnetic ring 3522 back to the initial position by virtue of its own elastic restoring force, so as to prepare for the next driving cycle. At the same time, in the process of the annular electromagnet 353 being powered on to attract the sliding magnetic ring 3522, the elastic element will also produce corresponding elastic deformation and store elastic potential energy. When the annular electromagnet 353 is powered off, the elastic element releases the stored elastic potential energy to assist the sliding magnetic ring 3522 to quickly return to the initial position, ensuring that the movement of the entire rotary drive system has good repeatability and stability, and can continuously and reliably drive the rotating cylinder 34 to perform precise rotational movement according to predetermined requirements under complex working conditions, thereby effectively regulating the overlap state of each notch in the partition assembly 3, and ensuring that the filtering and dust cleaning functions of the horizontal cloth drum dust collector can be accurately and efficiently realized.
[0051] like Fig.12As shown, the fixed bracket includes a fixing ring 3511 and a connecting column 3512; the fixing ring 3511 is arranged in the driving installation cavity 15 and is coaxial with the discharge barrel 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 installation 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 key reference for the precise positioning of the entire rotating drive member in the internal structure of the dust collector. The annular electromagnet 353 is coaxially mounted firmly in a predetermined space inside the fixed ring 3511. This coaxial layout ensures that the magnetic field generated by the annular electromagnet 353 can evenly and effectively act on the coaxial sliding magnetic ring 3522.
[0053] One end of the connecting column 3512 is reliably fixedly connected to the inner wall of the drive installation cavity 15, and the other end is firmly combined with the fixing ring 3511, so as to build a stable mechanical support structure between the fixing ring 3511 and the inner wall of the drive installation cavity 15, effectively ensuring the position stability and structural strength of the fixing ring 3511 in space. In the process of penetrating the sliding magnetic ring 3522, the connecting column 3512 forms a sliding penetration matching relationship with the sliding magnetic ring 3522. This design allows the sliding magnetic ring 3522 to slide axially on the connecting column 3512, and can also accurately limit and guide the movement trajectory of the sliding magnetic ring 3522.
[0054] The elastic reset element 354 is precisely arranged on the connecting column 3512 in the form of a set, and its spatial position is located between the sliding magnetic ring 3522 and the fixed ring 3511.
[0055] like Figure 6 , Fig.10 and Fig.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 chamber 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 The driving gear ring 53 is rotatably arranged in the driving installation cavity 15 and is coaxial with the transmission cylinder 51. 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 arranged on the outer circumferential surface of the transmission cylinder 51. The driven gear ring 55 can mesh with the driving gear ring 53. One end of the driven gear ring 55 is provided with a rotating magnetic ring 551 facing the annular electromagnet 353. 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 arranged in the driving installation cavity 15 and is drivingly connected to the driving gear ring 53 .
[0057] The spiral blade 52 is placed in the inner space of the central cavity 314 in a coaxially rotating manner, and one end of the spiral blade 52 extends into the interior 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, by virtue of its special spiral shape and spatial layout, the dust in the central cavity 314 can be gradually pushed to the collecting cavity 11 along the axial direction, thereby achieving effective cleaning and transfer of dust.
[0058] One end of the active gear ring 53 is configured with tooth grooves evenly distributed along its circumference, and these tooth grooves serve as key power transmission interfaces during the meshing transmission process between the active gear ring 53 and the driven gear ring 55 .
[0059] The driven gear ring 55 is cleverly arranged on the outer circumference of the transmission cylinder 51 in a coaxial interlocking and sliding manner, and can be laterally meshed with the tooth grooves of the active gear ring 53 under certain conditions, thereby establishing a power transmission connection between the two. When meshing occurs, the rotational movement of the active gear ring 53 can be transmitted to the driven gear ring 55 through the mutually meshing 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 realize 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 for guiding the driven gear ring 55 away from the tooth groove is arranged on the circumferential surface of the transmission cylinder 51. 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 component 5 for dust cleaning operation, 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, realizes the meshing of the driven gear ring 55 with the active gear ring 53, and thus starts the power transmission and motion execution process of the entire dust pushing component 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 Fig.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 slidably 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 Fig.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 driving installation cavity 15, and the worm 561 is meshed 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, 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 multiple active gear rings 53 to rotate, and can also drive a single active gear ring 53 to rotate. When a single partition component 3 needs to be started, the corresponding driven gear ring 55 is meshed with the corresponding and rotating active gear ring 53 to start a single partition component 3 in the same row. With this arrangement, firstly, the dust can be cleaned in a targeted manner at the dusty area; secondly, the dust can be discharged continuously after the dust cleaning is completed and the filtering stage is entered.
[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 arranged at the bottom of the processing bin 16. A receiving trough 17 located at the bottom of the discharge cylinder 33 is arranged in the collecting chamber 11, and an auger 18 extending into the processing bin 16 is arranged in the receiving trough 17. A synchronous belt 19 is arranged 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 material receiving trough 17, so that the rotating auger 18 pushes the dust in the material receiving trough 17 into the processing bin 16 and discharges it to the outside through the discharge port.
[0069] The synchronous belt 19 can drive and connect the auger 18 and the worm 561, thereby facilitating the transmission of torque.
[0070] like Figure 8 and Fig. 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 moves in 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 a 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 centrifugal force generated by the rotation of the spiral blades 52, the dust extracted 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 rotation angular velocity. During the high-speed rotation of the spiral blades 52, the dust particles obtain sufficient centrifugal force 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 by virtue of 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] A skeleton 42 is also provided in the cloth tube 4. A sleeve opening is provided at one end of the cloth tube 4 away from the air outlet 41. The cloth tube 4 is sleeved on the skeleton 42 through the sleeve opening. A sealing disk 43 is provided at the end of the skeleton 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, so that a new cloth tube 4 can be replaced.
[0074] A method for removing dust using a horizontal cloth drum 4 for 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 in 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. Then, it enters the clean chamber 13 through the air outlet 41. The clean air is discharged to the outside 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 outer air passage slot 312 and open the outer dust exhaust slot 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 outer dust exhaust slot 313 and falls into the collecting chamber 11.
[0077] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
