Description

Technical Field

[0001] This invention relates to the field of industrial dust removal equipment technology, specifically to a self-sensing continuous ash removal device for industrial dust removal equipment. Background Technology

[0002] Industrial dust collection equipment is a core component in industrial production, controlling dust pollution and ensuring the safety of the production environment and equipment. It is widely used in industries such as mining, metallurgy, chemicals, and building materials. Most existing industrial dust collection equipment employs a filtration-type structure. Dust-laden gas passes through a filter screen, where dust is trapped on the screen surface and falls into a collection box for collection, then is periodically discharged via a dust removal mechanism. However, existing industrial dust collection equipment suffers from the following problems during use: In actual use, the filtered dust adheres to the air inlet surface of the filter screen for a long time, and cannot be completely cleaned by airflow alone. This leads to increased filter screen resistance and decreased dust removal efficiency, requiring manual shutdown and cleaning, which affects the continuity of production. Secondly, the dust accumulates and compacts in the dust collection box, forming an arch structure that blocks the material discharge channel and causes ash discharge interruption. This requires manual breaking of the arches, which is labor-intensive and poses safety hazards. Furthermore, most equipment relies on manual observation or timed ash discharge, which cannot accurately sense the amount of ash collected. This can easily lead to problems such as untimely ash discharge, resulting in ash overflow or empty discharge that wastes energy. In addition, the traditional unloading valve has insufficient sealing performance when not discharging ash, causing the negative pressure of the dust removal system to be lost, reducing the dust removal effect, and causing dust leakage that pollutes the environment. Summary of the Invention

[0003] The purpose of this invention is to provide a self-sensing continuous ash discharge device for industrial dust removal equipment, so as to solve the problems mentioned in the background art.

The ash discharge sealing assembly includes a star-shaped discharge valve, a connecting seat, and a sealing movable plate. When the star-shaped discharge valve is not discharging ash, it seals the connecting seat through the sealing movable plate at the bottom to prevent air leakage from the dust removal equipment.

[0005] Optionally, the filter cleaning assembly further includes a drive motor, a drive shaft, and a drive pulley. The drive motor is fixedly installed on the top of the upper box, the drive shaft is rotatably connected to the middle of the upper box, the drive pulley is fixedly installed on one end of the drive shaft, one end of the drive shaft is fixedly installed on one end of the output shaft of the drive motor, and the drive motor is electrically connected to the control electrical box by wires.

[0006] Optionally, the first fixing bracket is fixedly installed on the inner side of the bottom of the mounting groove, the rotating shaft is rotatably connected to the middle of the first fixing bracket, the driven pulley is fixedly installed on one end of the rotating shaft, the cleaning brush is detachably installed on the other end of the rotating shaft, the cleaning brush is located inside the filter screen, and the driven pulley and the driving pulley are mutually driven by a belt.

[0008] Optionally, the second fixing frame is fixedly installed inside the ash collection box, the driven shaft is rotatably connected to the middle of the second fixing frame, and the arch-breaking anchor is fixedly installed at one end of the driven shaft.

[0009] Optionally, the hexagonal insert and the hexagonal slot are shaped to match, and one end of the hexagonal insert is inserted into the inside of the hexagonal slot.

[0011] Optionally, the control electrical box is fixedly installed on one side of the middle box, the material level sensor is fixedly installed in the middle of the second fixed frame, and the pressure sensor is fixedly installed between the ash collection box and the support arm. Both the material level sensor and the pressure sensor are electrically connected to the control electrical box by wires.

[0012] Optionally, the ash discharge sealing assembly further includes a sealing ring, a reducer, and a stepper motor. The sealing ring is fixedly installed on both sides of the sealing movable plate. The reducer is fixedly installed on one side of the connecting seat. The stepper motor is fixedly installed on one side of the reducer. One end of the stepper motor output shaft is fixedly installed on the input end of the reducer. The output end of the reducer is fixedly installed on one end of the fixed shaft of the sealing movable plate. The stepper motor is electrically connected to the control electrical box by a wire.

[0014] The present invention has at least the following beneficial effects: (1) This solution uses a filter cleaning component. Specifically, the control electrical box starts the drive motor at a preset cycle, which drives the cleaning brush to rotate via a belt drive, automatically cleaning the air inlet surface of the filter. No manual intervention or machine shutdown is required. The attached dust is stably removed at a set frequency, avoiding filter blockage that leads to increased wind resistance and decreased dust removal efficiency. This maintains the equipment's filtration performance for a long time and significantly reduces the intensity of manual maintenance and downtime losses. (2) This solution sets up a dust removal and arch breaking component. Specifically, it shares a power source with the filter screen cleaning. While cleaning the dust at regular intervals, it drives the arch breaking anchor to rotate, thereby periodically disturbing and loosening the dust in the dust collection box. The dust arches are periodically broken according to the equipment operation rules to prevent blockage of the material discharge channel, ensure smooth dust removal path throughout the process, eliminate the need for manual arch breaking, and improve the continuity of dust removal and the safety of equipment operation. (3) This solution sets up an ash collection and detection component. Specifically, based on timed ash discharge, the ash amount is monitored by both a level sensor and a pressure sensor, providing a safety threshold for timed control. This ensures stable ash discharge according to the set cycle and allows for timely adjustment when the ash amount is abnormal, avoiding ash overflow, empty discharge, or ash blockage. It achieves intelligent continuous ash discharge with timed control as the main method and detection as the auxiliary method, resulting in a high degree of automation and more reliable operation. (4) This solution uses a dust discharge sealing component. Specifically, the control electrical box controls the star-shaped unloading valve and the sealing movable plate to operate according to the dust discharge cycle. It opens precisely during dust discharge and closes immediately after dust discharge is completed. It works with the sealing ring to achieve a reliable seal, always maintaining a stable negative pressure in the dust removal system. The timed opening and closing actions are uniform and respond quickly, effectively preventing air leakage and dust overflow, and improving the airtightness and environmental protection of the equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6This invention provides a self-sensing continuous ash discharge device for industrial dust removal equipment, including a filter cleaning assembly, an ash discharge and arch breaking assembly, an ash collection detection assembly, and an ash discharge sealing assembly installed on an upper box 1, a middle box 2, and an ash collection box 3. The upper box 1 has an installation groove 101, and a filter screen 102 is installed inside the installation groove 101. A fixing cover 103 is detachably installed on the inner side of the top of the installation groove 101. A clean gas outlet 4 is opened on one side of the upper box 1, and a turbid gas inlet 5 is opened on one side of the middle box 2.

[0019] The filter cleaning assembly is located inside the upper box 1. The filter cleaning assembly includes a first fixing frame 604, a rotating shaft 605, a driven pulley 606, and a cleaning brush 607 located inside the mounting groove 101. The rotating shaft 605 drives the cleaning brush 607 to rotate and clean the dust adhering to the air inlet surface of the filter 102. In some embodiments, see Figure 2 , Figure 3 , Figure 4 The filter cleaning assembly also includes a drive motor 601, a drive shaft 602, and a drive pulley 603. The drive motor 601 is fixedly installed on the top of the upper box 1, the drive shaft 602 is rotatably connected to the middle of the upper box 1, the drive pulley 603 is fixedly installed on one end of the drive shaft 602, one end of the drive shaft 602 is fixedly installed on one end of the output shaft of the drive motor 601, the drive motor 601 is electrically connected to the control electrical box 801 by wires, the first fixing bracket 604 is fixedly installed on the inner side of the bottom of the mounting groove 101, the rotating shaft 605 is rotatably connected to the middle of the first fixing bracket 604, the driven pulley 606 is fixedly installed on one end of the rotating shaft 605, and the cleaning brush 607 is detachably installed on the other end of the rotating shaft 605. The cleaning brush 607 is located inside the filter 102, and the driven pulley 606 and the drive pulley 603 are mutually driven by a belt.

[0020] Understandably, the drive motor 601 is a speed-regulating geared motor of model 6IK200RGN-CF, and the control electrical box 801 has a built-in PLC controller of model S7-200SMART, which outputs drive signals at preset time intervals. When the drive motor 601 is running, it drives the drive shaft 602 and the active pulley 603 to rotate synchronously. Through belt transmission, it drives the driven pulley 606 and the rotating shaft 605 to rotate, so that the cleaning brush 607 performs circumferential cleaning along the inner side of the filter screen 102, brushing the attached dust onto the middle box 2 and settling it into the dust collection box 3. The first fixed frame 604 provides stable support for the rotating shaft 605. The fixed cover 103 has a detachable structure, which facilitates the maintenance and replacement of the filter screen 102 and the cleaning brush 607. The entire process does not require manual cleaning and ensures continuous operation of the equipment.

[0021] The dust removal and arch breaking component is located inside the dust collection box 3. The dust removal and arch breaking component includes a second fixed frame 702, a driven shaft 703 and an arch breaking anchor 705. The driven shaft 703 drives the arch breaking anchor 705 to rotate, disturbing the dust in the dust collection box 3 and preventing dust from bridging. In some embodiments, see Figure 3 , Figure 5 The ash discharge and arch breaking assembly includes a hexagonal insert shaft 701 and a hexagonal slot 704. The hexagonal insert shaft 701 is fixedly installed at one end of the drive shaft 602, and the hexagonal slot 704 is opened at one end of the driven shaft 703. The second fixing frame 702 is fixedly installed inside the ash collection box 3. The driven shaft 703 is rotatably connected to the middle of the second fixing frame 702. The arch breaking anchor 705 is fixedly installed at one end of the driven shaft 703. The hexagonal insert shaft 701 and the hexagonal slot 704 are matched in shape, and one end of the hexagonal insert shaft 701 is inserted into the inside of the hexagonal slot 704.

[0022] Understandably, the hexagonal insert 701 at the end of the drive shaft 602 is engaged with the hexagonal slot 704 of the driven shaft 703 to achieve coaxial and synchronous driving of the dust removal and arch breaking mechanisms, without the need for an additional independent power source. The driven shaft 703 is supported and positioned by the second fixed frame 702, and rotates periodically with the drive shaft 602, driving the arch breaking anchor 705 to disturb the dust in the dust collection box 3, periodically destroying the dust bridging structure. This linkage structure simplifies the transmission system, reduces energy consumption and failure rate, and operates synchronously with the timed dust removal cycle to ensure the continuous unobstructed flow of the ash discharge channel and avoid ash blockage and shutdown.

[0023] The dust collection and detection components are located inside and outside the dust collection box 3. The dust collection and detection components include a control electrical box 801, a material level sensor 802 and a pressure sensor 804. Through the cooperation of the material level sensor 802 and the pressure sensor 804, the overall weight and the amount of dust inside the dust collection box 3 are detected so that automatic dust discharge can be performed. In some embodiments, see Figure 5 The ash collection and detection assembly also includes a support arm 803, which is fixedly installed at the bottom of the ash collection box 3. The control electrical box 801 is fixedly installed on one side of the middle box 2. The material level sensor 802 is fixedly installed in the middle of the second fixed frame 702. The pressure sensor 804 is fixedly installed between the ash collection box 3 and the support arm 803. Both the material level sensor 802 and the pressure sensor 804 are electrically connected to the control electrical box 801 by wires.

[0024] Understandably, the level sensor 802 is a TL-YYC rotary paddle level detector, and the pressure sensor 804 is a DYLF-101. Both are connected to the PLC control system of the control electrical box 801. The level sensor 802 monitors the dust level in the dust collection box 3 in real time, and the pressure sensor 804 collects the dust weight signal through the support arm 803. The dual sensor data are checked together to provide a safety threshold for timed dust discharge. When the dust level exceeds the limit, emergency dust discharge is triggered. When the dust level is below the threshold, dust discharge is suspended. This realizes intelligent continuous dust discharge with timed discharge as the main method and detection as the auxiliary method, thereby improving operational reliability.

[0025] The ash discharge sealing assembly is located at the bottom of the ash collection box 3. The ash discharge sealing assembly includes a star-shaped discharge valve 901, a connecting seat 902 and a sealing movable plate 903. When the star-shaped discharge valve 901 is not discharging ash, it seals the connecting seat 902 through the sealing movable plate 903 at the bottom to prevent the dust removal equipment from leaking air. In some embodiments, see Figure 6 The ash discharge sealing assembly also includes a sealing ring 904, a reducer 905, and a stepper motor 906. The sealing ring 904 is fixedly installed on both sides of the sealing movable plate 903. The reducer 905 is fixedly installed on one side of the connecting seat 902. The stepper motor 906 is fixedly installed on one side of the reducer 905. One end of the output shaft of the stepper motor 906 is fixedly installed on the input end of the reducer 905. The output end of the reducer 905 is fixedly installed on one end of the fixed shaft of the sealing movable plate 903. The stepper motor 906 is electrically connected to the control electrical box 801 by a wire. The input end of the star-shaped discharge valve 901 is fixedly installed at the bottom of the ash collection box 3. The connecting seat 902 is fixedly installed on the output end of the star-shaped discharge valve 901. The sealing movable plate 903 is rotatably connected to the inside of the connecting seat 902. The star-shaped discharge valve 901 is electrically connected to the control electrical box 801 by a wire.

[0026] Understandably, the stepper motor 906 is model 42BYGH250-27A, the reducer 905 has a reduction ratio of 1:50, and the star-shaped unloading valve 901 is model YJD-06. The control electrical box 801 drives the stepper motor 906 according to the ash discharge cycle, which drives the sealing movable plate 903 to rotate and open and close via the reducer 905. The sealing ring 904 enhances the sealing surface fit. When ash is discharged, the sealing movable plate 903 opens, and the star-shaped unloading valve 901 discharges material simultaneously. After the ash discharge is completed, it closes immediately. The double seal ensures the stability of the negative pressure inside the upper box 1 and the middle box 2, preventing air leakage and dust overflow.

[0027] The working process and principle of this invention: Dust-laden gas enters the middle chamber 2 through the turbid gas inlet 5, and after being filtered by the filter screen 102 in the upper chamber 1, the clean gas is discharged through the clean gas outlet 4. Dust is trapped on the surface of the filter screen 102 and settles into the dust collection box 3 for collection. The control electrical box 801 starts the drive motor 601 at a preset time, which drives the cleaning brush 607 to rotate and clean the filter screen 102 through the drive pulley 603 and the driven pulley 606. At the same time, the hexagonal insert shaft 701 is linked with the driven shaft 703 and the arch-breaking anchor. 705 rotates synchronously to break up and loosen the dust in the dust collection box 3 at regular intervals; the material level sensor 802 and the pressure sensor 804 monitor the amount and weight of dust in real time. When the dust discharge conditions are met, the control electrical box 801 starts the star-shaped unloading valve 901 at regular intervals and drives the stepper motor 906 to open the sealing movable plate 903 to discharge dust. After the dust discharge is completed, the sealing movable plate 903 closes and restores the equipment to the sealed state. The cycle realizes the integrated operation of timed dust cleaning, timed arch breaking, self-sensing continuous dust discharge, and sealing to prevent leakage.
