Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a bag filter dust collector for a crushing line. Background Technology

[0002] A crushing line is a highly efficient material handling process, widely used in industries such as mining, construction, and chemicals. It mainly consists of crushers, conveying equipment, and screening devices, capable of gradually crushing large materials into the required small particles or powder. Crushing lines not only improve production efficiency but also optimize subsequent material processing and utilization. During the crushing process, materials are gradually reduced in particle size by different levels of crushers, while conveying equipment ensures continuous and stable material flow. The screening device ensures that the final product's particle size meets requirements. Furthermore, crushing lines are equipped with advanced control systems to achieve automated operation, reducing labor costs and intensity. Baghouse dust collectors are a key environmental protection device on crushing lines. Crushing operations generate a large amount of dust, and baghouse dust collectors filter dust-laden gas through filter bags, effectively intercepting dust and ensuring that emissions meet environmental standards.

[0003] Chinese Patent CN211913075U discloses a bag filter dust collector, including a support frame, a dust collector housing fixed on the support frame, an air inlet at the bottom of one side of the dust collector housing, and an air outlet at the top of the other side of the dust collector housing. The planes where the air inlet and the air outlet are located are symmetrical. A dust hopper is connected to the bottom of the dust collector housing. A partition is installed inside the dust collector housing, and a fixing frame is fixed to the lower surface of the partition. A dust collector bag is fitted on the outer wall of the fixing frame. The dust collector bag is connected to the partition. An impact device is installed between the partition and the top of the dust collector housing. A jet blowing device is installed inside the dust collector bag.

[0004] While the above-mentioned solutions effectively remove dust from the outside of the filter bags and improve the efficiency of the baghouse dust collector, and although collection boxes are installed, workers on the crushing line typically face intense and heavy workloads. Their attention is mainly focused on the operation of the equipment and the production progress, making it difficult to constantly monitor the dust accumulation in the collection boxes. Once the dust in the collection boxes reaches or exceeds the capacity limit, and the workers fail to detect and handle it in time, dust overflow can easily occur. This not only affects the normal operation of the baghouse dust collector but may also have adverse effects on the production environment and the health of the workers. Therefore, it does not meet the existing needs. In response, we propose a baghouse dust collector for crushing lines. Utility Model Content

[0005] The purpose of this utility model is to provide a bag filter dust collector for a crushing line, so as to solve the problem mentioned in the background art that the lack of a reminder function in the bag filter dust collectors leads to the need for operators to pay attention to the collection situation to improve work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bag filter dust collector for a crushing line, comprising a dust collector body, a dust collection chamber inside the dust collector body, a top cover at the upper end of the dust collector body, the top cover fitting snugly against the dust collector body, an annular support plate on the upper side of the inner wall of the dust collection chamber, a partition plate at the upper end of the annular support plate fitting snugly against the annular support plate, a plurality of dust collection bags installed at the lower end of the partition plate, a collection box at the lower end of the dust collector body, and the dust collection chamber communicating with the collection box, a lifting plate inside the collection box, a collection container at the upper end of the lifting plate fitting snugly against the lifting plate, a pressure sensor installed at the middle position of the lower end inside the collection container, an air inlet pipe on one side of the dust collector body, and the air inlet pipe communicating with the dust collection chamber, and an air outlet pipe inside the top cover.

[0007] Preferably, guide rods are welded at the four corners inside the collection box, the guide rods all penetrate the lifting plate and slide with the lifting plate, and a return spring is sleeved on the upper side of the outside of the guide rods. One end of the return spring is connected to the lifting plate and the other end of the return spring is connected to the collection box.

[0008] Preferably, a PLC controller is installed on one side of the collection box, and the input terminal of the PLC controller is electrically connected to the output terminal of the pressure sensor. An alarm is installed on one side of the top cover, and the input terminal of the alarm is electrically connected to the output terminal of the PLC controller.

[0009] Preferably, four first electric telescopic rods are provided on the upper side of the exterior of the dust collector body in a ring-shaped equidistant arrangement. The first electric telescopic rods are all fixedly connected to the dust collector body, and the output ends of the first electric telescopic rods are all connected to the top cover.

[0010] Preferably, a second electric telescopic rod is provided at the lower end of the interior of the dust collector body, and a conical block is provided at the output end of the second electric telescopic rod.

[0011] Preferably, a sealing ring is adhered and fixed to the outer side of the lower end of the top cover, and an annular abutment is adhered and fixed to the inner side of the lower end of the top cover.

[0012] Preferably, the front end of the collection box is equipped with a rotating door.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a collection box at the lower end of the dust collector body. When dust from the dust collection chamber falls into the collection box, it enters the collection box and moves downwards under gravity. Once enough dust has been collected, the lower end of the collection box rests on a pressure sensor. The pressure sensor detects the pressure and sends an electrical signal to the PLC controller. The PLC controller then activates an alarm to alert nearby operators. Operators can then remove the collection box for cleaning by opening the rotating door, thus reducing manual intervention, lowering the workload of operators, and allowing them to focus more on the crushing line.

[0015] 2. This utility model features four first electric telescopic rods arranged in a ring at equal intervals on the upper side of the dust collector body. When cleaning the dust collection chamber is required, the first electric telescopic rods can be activated, causing the top cover to move upward. This upward movement of the top cover causes the ring-shaped abutment to press against the partition. The operator can easily remove the partition from the ring-shaped support plate with a simple pull, without using any tools or applying excessive force. This saves cleaning time, reduces operational difficulty, and allows even operators lacking professional experience to quickly get started.

[0016] 3. This utility model features a second electric telescopic rod installed at the lower end of the dust collector body, with a sealing ring adhered and fixed to the outer side of the lower end of the top cover. During dust removal, the top cover fits tightly against the dust collector body, while the sealing ring adheres to the upper end of the outer wall of the dust collector body, increasing the sealing performance of the dust collector body and effectively preventing dust from escaping during the dust removal process. Simultaneously, during dust removal, the conical block at the upper end of the second electric telescopic rod can move downwards, thereby sealing the lower end of the dust collector body and preventing airflow from directly entering the collection box during the dust removal process, thus avoiding secondary dust re-entrainment caused by airflow disturbance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a bag filter dust collector for a crushing line, comprising a dust collector body 1, a dust collection chamber 3 inside the dust collector body 1, a top cover 2 at the upper end of the dust collector body 1, the top cover 2 fitting snugly against the dust collector body 1, an annular support plate 6 on the upper side of the inner wall of the dust collection chamber 3, a partition 4 at the upper end of the annular support plate 6, the partition 4 fitting snugly against the annular support plate 6, and a plurality of dust collection bags 5 installed at the lower end of the partition 4 for dust collection. A collection box 12 is provided at the lower end of the main body 1, and the dust removal chamber 3 is connected to the collection box 12. A lifting plate 17 is provided inside the collection box 12, and a collection box 18 is provided at the upper end of the lifting plate 17. The collection box 18 is attached to the lifting plate 17. A pressure sensor 19 is installed at the middle position of the lower end inside the collection box 12. An air inlet pipe 20 is provided on one side of the main body 1 of the dust collector, and the air inlet pipe 20 is connected to the dust removal chamber 3. An air outlet pipe 21 is provided inside the top cover 2.

[0024] During operation, the air inlet pipe 20 supplies air to the dust removal chamber 3, the dust removal bag 5 filters the dust, and the second electric telescopic rod 10 drives the conical block 11 to seal the lower opening, ensuring that the airflow is purified by the bag and discharged through the air outlet pipe 21, preventing dust from escaping. After dust removal, the conical block 11 moves upward, and the dust falls into the collection box 18 of the collection box 12. When the collection box is full, the lifting plate 17 moves downward to compress the reset spring 16, triggering the pressure sensor 19. The PLC controller 13 activates the alarm 14 to remind the user to clean the dust, opens the rotating door 22, and presses down the lifting plate to remove the collection box 18 for cleaning. This reduces manual intervention, lowers the labor intensity of operators, and allows operators to devote more energy to the crushing line.

[0025] Please see Figure 4Guide rods 15 are welded at the four corners inside the collection box 12. The guide rods 15 all pass through the lifting plate 17 and slide with the lifting plate 17. A return spring 16 is sleeved on the upper side of the outside of the guide rods 15. One end of the return spring 16 is connected to the lifting plate 17 and the other end of the return spring 16 is connected to the collection box 12. The guide rods 15 provide a stable sliding track for the lifting plate 17, ensuring the stability and accuracy of the lifting plate 17 during movement. At the same time, the return spring 16 can provide elastic support after the lifting plate 17 moves down, which facilitates the reset of the lifting plate 17 and the collection box 18.

[0026] Please see Figure 1 and Figure 2 A PLC controller 13 is installed on one side of the collection box 12, and the input terminal of the PLC controller 13 is electrically connected to the output terminal of the pressure sensor 19. An alarm 14 is installed on one side of the top cover 2, and the input terminal of the alarm 14 is electrically connected to the output terminal of the PLC controller 13. The PLC controller 13 can receive the pressure signal transmitted by the pressure sensor 19 in real time, and determine whether the alarm 14 needs to be activated according to the preset logic. This realizes intelligent monitoring and alarm prompts of dust collection, and improves the automation level and ease of operation of the equipment.

[0027] Please see Figure 1 Four first electric telescopic rods 9 are arranged in a ring at equal intervals on the upper side of the dust collector body 1. The first electric telescopic rods 9 are all fixedly connected to the dust collector body 1, and the output end of the first electric telescopic rods 9 is connected to the top cover 2. The first electric telescopic rods 9 can stably and evenly drive the top cover 2 to move up and down, thereby realizing the rapid opening and closing of the space above the dust collector bag 5, which is convenient for cleaning and maintenance of the dust collection chamber 3.

[0028] Please see Figure 2 The lower end of the dust collector body 1 is provided with a second electric telescopic rod 10, and the output end of the second electric telescopic rod 10 is provided with a cone block 11. The second electric telescopic rod 10 can drive the cone block 11 to move up and down, thereby realizing the opening and closing control of the outlet below the dust collector bag 5, effectively preventing the problem of dust escaping during the dust removal process.

[0029] Please see Figure 1 , Figure 2 and Figure 3 A sealing ring 8 is bonded and fixed to the outer side of the lower end of the top cover 2, and an annular abutment 7 is bonded and fixed to the inner side of the lower end of the top cover 2. The sealing ring 8 can ensure the sealing between the top cover 2 and the dust collector body 1 to prevent the leakage of airflow and dust, while the annular abutment 7 can press tightly against the partition 4 when the top cover 2 is closed to achieve the function of fixing the partition 4.

[0030] Please see Figure 1 The front end of the collection box 12 is equipped with a rotating door 22. The opening and closing of the rotating door 22 is simple and quick, making it convenient for operators to clean the inside of the collection box 12 and replace the collection box 18.

[0031] Working principle: During use, airflow is introduced into the dust collection chamber 3 through the air inlet pipe 20. The dust collector bag 5 removes dust from the airflow. At this time, the sealing ring 8 is tightly attached to the outer wall of the dust collector body 1. The second electric telescopic rod 10 causes the cone block 11 to move downward, allowing the airflow to pass smoothly through the dust collector bag 5 and be discharged through the air outlet pipe 21, preventing dust from escaping. After dust removal is completed, the second electric telescopic rod 10 can be activated to move the cone block 11 upward, allowing the collected dust to enter the collection box 12 through the through hole. The dust will fall into the collection box 18. As the dust is collected, the collection box 18 will drive the lifting plate 17 to move downward. The lifting plate 17 is guided by the guide rod 15 wire to prevent directional deviation during movement. The downward movement of the lifting plate 17 will compress the return spring 16. When enough dust is collected, the lower end of the lifting plate 17 will press the pressure sensor 19. After the pressure sensor 19 detects the pressure, it will send an electrical signal to the PLC controller 13. After processing, the alarm 14 will be activated, attracting nearby operators to promptly clean the dust. By opening the rotating door 22 and pressing down the lifting plate 17, the collection box 18 can be removed for cleaning. After placing the empty collection box 18 on the upper end of the lifting plate 17, the lifting plate 17 will move the collection box 18 upward under the elastic action of the return spring 16, so that the upper end of the collection box 18 contacts the collection box 12, ensuring the stability of the collection box 18. When it is necessary to clean the inside of the dust removal chamber 3 after long-term use, the first electric telescopic rod 9 can be activated. The first electric telescopic rod 9 will move the top cover 2 upward, and the upward movement of the top cover 2 will move the annular stop block 7 upward simultaneously, thereby releasing the compression and fixation of the partition 4. The operator only needs to grasp the partition 4 to remove it from the annular support plate 6 without using any tools or applying excessive force, thus saving cleaning time, reducing the difficulty of operation, and facilitating quick cleaning.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
