Description

Technical Field

[0001] The invention belongs to the technical field of dust removal equipment, and in particular is a vibration bag dust removal equipment capable of monitoring pressure in real time. Background Art

[0002] A bag dust collector is a device that separates dust from flue gas. A bag dust collector, also known as a filter dust collector, is a dry and efficient dust collector. It is a dust removal device that uses bag filter elements made of fiber woven materials to capture solid particles in dust-containing gases. Its working principle is that dust particles are intercepted when they collide with the fibers due to inertia when they pass around the filter cloth fibers.

[0003] When in use, traditional bag-type dust removal equipment lacks the function of real-time monitoring of internal pressure, making it difficult to accurately assess the operating status of the equipment, which may lead to equipment failure or energy waste. It only uses a single filtering method, making it difficult to comprehensively and effectively filter dust particles of different sizes, resulting in incomplete dust removal. When the dust bags are vibrated to clean, the dust bags cannot be cleaned evenly, resulting in dust residue in some areas, affecting the air permeability of the dust bags and the overall dust removal efficiency. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention provides a vibrating bag dust removal device capable of monitoring pressure in real time.

[0005] The technical solution of the present invention is: a vibrating bag dust removal device capable of real-time pressure monitoring, comprising a dust removal housing with an air inlet and an air outlet respectively arranged on the left and right sides of the side wall, a ash hopper arranged at the bottom end of the dust removal housing, a bag dust removal component arranged in the dust removal housing and located between the air inlet and the air outlet, a vibration component connected to the bag dust removal component, and a pressure monitoring component arranged on the dust removal housing;

A vibrating ball is provided on the side of the V-shaped connecting rod close to the dust bag, and each of the second vertical mounting rods is evenly provided with shifting rods corresponding to the V-shaped connecting rods from top to bottom.

[0009] Furthermore, a supporting base is provided at the bottom end of the dust removal shell, and a dust collecting box that can slide up and down is movably connected to the supporting base, and each side wall of the ash hopper is provided with a limiting sliding vertical groove, and the upper end of the ash collecting box is provided with a sliding opening with the same size as the opening of the bottom end of the ash hopper, and each side wall of the sliding opening is provided with a sliding bar that is slidably connected to the limiting sliding vertical groove in a one-to-one correspondence, and an automatic opening and closing plate is provided at the bottom of the ash collecting box.

[0010] Description: The bottom end of the dust collector shell is supported by a supporting base to increase the bottom stability of the dust collector shell. The ash box and the outer wall of the ash hopper are connected by a sliding limiter between a sliding bar and a limit sliding vertical groove, which facilitates the ash box to slide up and down along the vertical groove outside the ash hopper, providing a larger storage space when dumping dust. When the ash box is full of ash, open the automatic opening and closing plate to clean it.

[0011] Furthermore, a transparent observation window is provided on the side wall of the ash collecting box.

[0012] Note: Through the transparent observation window, it is convenient to observe whether the ash box is full of ash, so that it can be cleaned immediately to ensure the normal use of the ash box.

[0013] Furthermore, a scraping assembly is provided at the bottom end of the ash hopper, and an annular mounting groove is provided on the inner wall of the ash hopper. The scraping assembly includes an annular mounting ring rotatably connected to the inside of the annular mounting groove, a plurality of scraping strips circumferentially arranged on the inner wall of the annular mounting ring, an annular closing ring arranged on the outer wall of the ash hopper and located at the position of the annular mounting groove, a pushing rod that passes through the annular closing ring and the annular mounting groove on one side and is connected to the annular mounting ring, and a sliding groove is provided on the side wall of the annular closing ring along the circumferential direction.

[0014] Description: When the inner wall of the ash hopper needs to be cleaned, the staff holds the push rod and pushes it to rotate along the sliding groove.

[0017] Furthermore, the dust filter is formed by splicing a plurality of filter drawers passing through the dust removal shell, and a dust filter plate is provided at the bottom of each filter drawer, and a pull-out handle is provided on the outer wall of the filter drawer. Each filter drawer is provided with an installation notch at the joint, and each installation notch is spliced ​​at a passage opening located on the periphery of the drive shaft.

[0018] Description: The gas treated by each dust bag is filtered again by the dust filter screen to increase the thoroughness of the dust removal effect. When each filter drawer needs to be cleaned, it can be pulled out by pulling the handle. The through openings formed by each installation notch for accommodating the drive shaft facilitate the normal rotation of the driving shaft driven by the rotating motor, ensuring the reliable operation of the vibration component.

[0019] Furthermore, each side wall of the filter drawer is provided with a sealing strip.

[0020] Note: By setting sealing strips on each side wall of the filter drawer, the sealing of the filter drawer installation is increased to ensure that dust does not flow to the outside through the gaps, thereby ensuring the dust removal effect.

[0021] Furthermore, a suction fan is provided at the air inlet, and a reducing pipe is provided at the air outlet.

[0022] Description: When performing dust removal work, the negative pressure provided by the suction fan can effectively suck the dust and particulate matter generated in the working area into the dust removal housing through the air inlet, which helps to reduce the suspended particles in the air and keep the working environment clean. The reducer at the air outlet is mainly used to smooth the transition of the airflow and reduce the sudden change of airflow speed, thereby reducing the pressure loss and turbulence formation inside the system, improving the aerodynamic efficiency of the entire equipment, reducing noise, and ensuring that the airflow is delivered to the designated area more evenly.

[0023] Furthermore, the pressure monitoring component includes a PLC controller arranged on the dust removal housing, a pressure sensor, a differential pressure gauge and a temperature sensor arranged on the dust removal housing and connected to the PLC controller.

[0024] Description: When the vibrating bag dust removal equipment is working, the pressure inside the dust removal shell is detected in real time through the pressure sensor, and the detected pressure signal is transmitted to the PLC controller. The pressure difference before and after the dust bag is measured by the differential pressure gauge. If the bag is blocked, the pressure difference will change. The differential pressure gauge will accurately measure the pressure difference value and transmit it to the PLC controller. The temperature of the dust removal equipment during operation is monitored by the temperature sensor and transmitted to the PLC controller. The PLC controller receives signals from the pressure sensor, differential pressure gauge and temperature sensor, analyzes and processes these signals, and makes corresponding control decisions.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) When the vibrating bag dust removal device capable of real-time pressure monitoring of the present invention is in use, the dust with large particles and high specific gravity in the dust-containing gas settles down due to the action of gravity and falls into the ash hopper for discharge. Other gases containing finer dust are filtered through each dust removal bag and the dust is retained on the dust removal bag. The gas treated by each dust removal bag is filtered again by the dust filter screen, thereby improving the thoroughness of dust removal and ensuring that the dust content of the discharged gas is extremely low. In addition, during the dust removal process, the pressure inside the dust removal housing is detected in real time by the pressure monitoring component, which can ensure that the equipment operates within a safe pressure range. The pressure difference before and after the dust removal bag is measured to promptly detect the performance degradation of the dust removal bag so that it can be cleaned or replaced in time to ensure the dust removal effect. Monitoring the temperature during the operation of the dust removal equipment can prevent the equipment from being damaged due to overheating, thereby troubleshooting hidden dangers of equipment failure.

[0027] (2) When the equipment needs to clean the dust bags, each V-shaped connecting rod will repeatedly hit each lever located in the same horizontal direction during the rotation process, so that one end of the vibrating ball will repeatedly vibrate the outer wall of the dust bag, thereby cleaning the dust on the dust bag. The vibration of the vibrating ball is relatively gentle. While effectively cleaning the dust, it can reduce the physical damage to the dust bag, extend the service life of the dust bag, and reduce the maintenance cost of the equipment. The V-shaped connecting rod repeatedly hits the lever during the rotation process, converting the rotational motion into a vibrating action on the vibrating ball. The structure is simple and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The vibration assembly 4 includes five ring gears 40 arranged at the upper end of the bag mounting plate 31 and rotatably connected to the outer wall of each mounting bracket 32, five rotating mounting frames 41 arranged at the periphery of each dust removal bag 33 and the upper end of which is connected to the bottom end of the corresponding ring gear 40, a fixed mounting frame 42 arranged at the bottom end of the bag mounting plate 31 and located at the periphery of each rotating mounting frame 41, a rotating motor 43 arranged at the upper end of the dust removal housing 1, a driving shaft 44 whose upper end is connected to the rotating motor 43 and whose bottom end passes through the dust filter 34 and is connected to the upper end of one of the mounting brackets 32 through an inverted U-shaped connecting frame 440, and the fixed mounting frame 42 is formed by four second vertical mounting rods 420 distributed circumferentially along the periphery of the rotating mounting frame 41, wherein the ring gear 40, the rotating motor 43 and the driving shaft 44 all adopt existing technologies, for example, the ring gear 40 can adopt the model HNL240, the rotating motor 43 can adopt the model DSM servo motor, and the driving shaft 44 can adopt the B-type shaft;

[0042] Two adjacent ring gears 40 mesh with each other, and the rotating mounting frame 41 is evenly rotated from top to bottom with 7 V-shaped connecting rods 411 with openings downward, and a vibrating ball 412 is provided on the V-shaped connecting rod 411 near the dust bag 33, and each second vertical mounting rod 420 is evenly provided with a lever 413 corresponding to the V-shaped connecting rod 411 from top to bottom;

The gas treated by each dust bag 33 is filtered again by the dust filter screen plate 341, thereby increasing the thoroughness of the dust removal effect. When each filter drawer 340 needs to be cleaned, it only needs to be pulled out through the pull-out handle 342.

[0047] Embodiment 2: This embodiment describes a working method of a vibrating bag dust removal device capable of real-time pressure monitoring, based on a vibrating bag dust removal device capable of real-time pressure monitoring of embodiment 1, comprising the following steps:

[0048] S1. When performing dust removal, the dust-containing gas in the working area is sucked into the dust removal housing 1 through the air inlet 10 by the negative pressure provided by the suction fan 14;

[0049] S2. Dust with large particles and high specific gravity in the dust-containing gas entering the dust removal housing 1 settles down due to gravity and falls into the ash hopper 2 for discharge. Other gases containing finer dust enter the dust removal bags 33 through the bottom ends of the dust removal bags 33, are filtered by the dust removal bags 33, and the dust is left on the dust removal bags 33. The gas treated by the dust removal bags 33 is filtered again by the dust filter screen 341, and then discharged through the air outlet 11.

[0050] S3. When the dust bag 33 needs to be cleaned, the driving shaft 44, the mounting bracket 32 ​​connected to the driving shaft 44, and the ring gear 40 arranged on the outer wall of the mounting bracket 32 ​​are driven to rotate by the rotating motor 43. Since the two adjacent ring gears 40 are meshed with each other, the ring gears 40 rotate synchronously. At this time, the rotating mounting frame 41 connected to the bottom end of the ring gear 40 also rotates, and the V-shaped connecting rods 411 arranged on the rotating mounting frame 41 will repeatedly hit the levers 413 located in the same horizontal direction during the rotation process, so that one end of the vibrating ball 412 repeatedly vibrates the outer wall of the dust bag 33, thereby cleaning the dust on the dust bag 33, and the cleaned dust falls out through the ash hopper 2.

[0051] S4. During the dust removal process, the pressure inside the dust removal housing 1 is detected in real time through the pressure sensor 51, and the detected pressure signal is transmitted to the PLC controller 50. The pressure difference before and after the dust bag 33 is measured by the differential pressure gauge 52. If the bag is blocked, the pressure difference will change. The differential pressure gauge 52 will accurately measure the pressure difference value and transmit it to the PLC controller 50. The temperature of the dust removal equipment during operation is monitored by the temperature sensor 53 and transmitted to the PLC controller 50. The PLC controller 50 receives signals from the pressure sensor 51, the differential pressure gauge 52 and the temperature sensor 53, analyzes and processes these signals, and makes corresponding control decisions.

[0052] Embodiment 3: This embodiment differs from Embodiment 1 in that:

[0053] like Figure 4 , 5 As shown, a support frame 12 is provided at the bottom of the dust collecting housing 1, and an ash collecting box 13 that can slide up and down is movably connected to the support frame 12. A limit sliding vertical groove 20 is provided on each side wall of the ash hopper 2.

An automatic opening and closing plate 132 is provided at the bottom of the ash collecting box 13, and the bottom of the dust collecting housing 1 is opened and closed by the support frame 12. The support is provided to increase the bottom stability of the dust removal housing 1. The ash box 13 and the outer wall of the ash hopper 2 are connected by a sliding limiter between the sliding bar 131 and the limit sliding vertical groove 20, which facilitates the ash box 13 to slide up and down along the vertical groove outside the ash hopper 2, providing a larger storage space when dumping dust. When the ash box 13 is full of ash, the automatic opening and closing plate 132 can be opened for cleaning. The automatic opening and closing plate 132 adopts the existing technology, for example, the model that can be used is ANNY1202;

[0054] A transparent observation window 133 is provided on the side wall of the ash collecting box 13 , through which it is convenient to observe whether the ash collecting box 13 is full of ash, so that it can be cleaned immediately to ensure the normal use of the ash collecting box 13 .

[0055] Embodiment 4: This embodiment differs from Embodiment 2 in that:

[0056] In step S3, the cleaned dust falls out of the ash hopper 2 and falls into the ash box 13. The transparent observation window 133 is used to observe whether the ash box 13 is full of ash. When the ash box 13 is full of ash, the automatic opening and closing plate 132 is opened for cleaning. During this process, as the dust entering the ash box 13 gradually increases, the sliding bar 131 slides downward in the limit sliding vertical groove 20 to make the ash box 13 move downward, thereby achieving the purpose of adjusting the dust storage space.

A sliding groove 214 is provided on the side wall of the annular closed ring 212 along the circumferential direction. When the inner wall of the ash hopper 2 needs to be cleaned, the staff holds the push rod 213 and pushes it to rotate along the sliding groove 214. At this time, the annular mounting ring 210 will also rotate synchronously in the annular mounting groove 22, and the scraping strips 211 connected to the annular mounting ring 210 will rotate along the inner wall of the ash hopper 2, and effectively scrape the stubborn stains, agglomerated dust, etc. on the inner wall of the ash hopper 2. The structure is simple, the operation is convenient, and the cleaning is thorough.

[0058] A pushing ball 215 is provided on the pushing rod 213 on the side opposite to the annular mounting ring 210, and the scraping strips 211 are distributed along the height direction of the inner wall of the ash hopper 2. The staff can rotate the pushing rod 213 along the sliding groove 214 by holding the pushing ball 215, conveniently holding and applying force, thereby easily rotating the pushing rod 213.

[0059] Embodiment 6: This embodiment differs from Embodiment 4 in that: it also includes step S5;

[0060] S5. When the inner wall of the ash hopper 2 needs to be cleaned, the staff holds the pushing ball 215 to rotate the pushing rod 213 along the sliding groove 214.
