Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, and in particular relates to a dust hopper device for collecting dust. Background Technology

[0002] An electrostatic precipitator (ESP) is a highly efficient gas purification device widely used in industries such as power, metallurgy, and chemicals to remove dust particles from industrial flue gas. Its basic principle involves applying a high-voltage direct current to two metal anodes (collecting electrodes) and cathodes (corona electrodes) with significantly different radii of curvature, creating a non-uniform electric field that ionizes the gas. The electrons, anions, and cations generated by ionization are adsorbed onto dust particles passing through the electric field, charging them. Under the influence of the electric field, the charged dust particles move towards the electrodes with opposite polarity and eventually deposit on the electrode surface, thus achieving gas-solid separation. When the dust deposited on the electrodes reaches a certain thickness, it is detached by a rapping mechanism and falls by gravity into the ash hopper at the bottom of the ESP for temporary storage, followed by centralized treatment. The ash hopper, a key component of the ESP, has the core function of collecting and temporarily storing the dust detached from the electrodes and ensuring that the dust can be smoothly and continuously discharged from the system, guaranteeing the stable and efficient operation of the ESP. Currently, traditional ash hopper discharge methods mostly use rigid connections or flanges directly connected to the ash discharge valve or ash conveying equipment (such as screw conveyors, scraper conveyors, etc.). When dust needs to be removed, the ash discharge valve must be opened to allow the dust to fall directly into the transport vehicle below.

[0003] However, this traditional ash removal method has significant technical drawbacks: First, during the ash removal process, the dust discharge port of the ash hopper is directly or indirectly connected to the atmosphere, causing a large amount of external air to be drawn into the electrostatic precipitator. This reverse airflow severely disrupts the normal airflow distribution and electric field stability inside the electrostatic precipitator, potentially causing the collected dust to be re-entrained into the flue gas, leading to a decrease in dust removal efficiency and increasing fan load and energy consumption. Second, dust (especially dust with high moisture content or adhesiveness) is prone to bridging or arching at the bottom of the ash hopper, resulting in poor ash removal or even blockage, affecting the continuous operation of the entire dust removal system. In such cases, manual intervention is usually required, posing safety risks and being inconvenient to operate. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a dust hopper device for collecting dust, which solves the problems of easy air leakage in the dust hopper of electrostatic precipitators during dust discharge, resulting in a decrease in dust removal efficiency, and the dust being easily blocked and difficult to discharge smoothly.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A dust hopper device for collecting dust includes: a connecting cylinder, a shielding mechanism, and a carrying hopper; One end of the connecting cylinder is connected to the ash discharge end of the electrostatic precipitator, and the other end is detachably connected to the bearing hopper. The bearing hopper has a receiving cavity, which is connected to the ash discharge channel of the connecting cylinder. The shielding mechanism includes a baffle, a rotating shaft, a bearing seat, and a locking assembly. The rotating shaft is fixedly connected to the baffle, the bearing seat is disposed on the connecting cylinder, the rotating shaft is connected to the bearing seat, the baffle is disposed within the ash discharge channel, and the locking assembly includes a locking gear and a locking unit. Part of the rotating shaft extends through the bearing seat to the outside of the ash discharge channel and is fixedly connected to the locking gear. The locking unit is disposed on the outer wall of the connecting cylinder and is used to lock and fix the locking gear so that the baffle is lockably rotatably connected within the ash discharge channel.

[0006] Furthermore, the locking unit includes a first locking plate, a second locking plate, a stop plate, a pull rod, a locking plug, and a locking spring; The first locking plate and the second locking plate are both fixedly connected to the outer wall of the connecting cylinder. The locking plug and the stop plate are both fixedly connected to the pull rod. The first locking plate and the second locking plate are both provided with through holes for the pull rod to pass through. The stop plate and the locking spring are both located between the first locking plate and the second locking plate. The locking spring is sleeved on the pull rod. The locking plug is provided with a locking slot corresponding to the tooth groove of the locking gear.

[0007] Furthermore, the locking unit includes a pull ring, which is disposed at the end of the pull rod opposite to the locking plug.

[0008] Furthermore, the locking unit includes a limiting pin; The pull rod has a locked state and a released state. The pull rod is provided with an anti-shrinkage hole. The second locking plate is provided with a first limiting plate and a second limiting plate. The pull rod is located between the first limiting plate and the second limiting plate. Both the first limiting plate and the second limiting plate are provided with limiting holes corresponding to the anti-shrinkage hole. When the lever is in the locked state, the locking slot of the locking plug engages with one of the teeth of the locking gear. When the pull rod is in the released state, the anti-shrinkage hole and the limiting hole are coaxially arranged so that the limiting pin passes through the first limiting plate, the pull rod and the second limiting plate at the same time.

[0009] Furthermore, the cross-section of the pull rod is square, and the cross-section of the through hole is square.

[0010] Furthermore, the baffle is provided with a mounting ring groove for mounting a scraper; A handle is installed at the end of the rotating shaft located outside the ash discharge channel.

[0011] Furthermore, the connecting cylinder includes a connecting section and a discharge section; The shielding mechanism is disposed on the connecting section, and the end of the discharge section opposite to the connecting section is detachably connected to the bearing bucket. From the connecting section toward the discharge section, the cross-sectional area of ​​the discharge section gradually increases.

[0012] Furthermore, the bearing bucket includes a fixed abutment ring plate and a bearing body, and a plug is fixedly connected to one end of the discharge section away from the connecting section. The plug has a plug groove for the abutment ring plate to be inserted into. The abutment ring plate is provided with an embedded ring groove for installing a rubber gasket.

[0013] Furthermore, the bottom surface of the connector is provided with a plurality of fixing posts, and the fixing posts have screw holes communicating with the connector slot.

[0014] Furthermore, the bottom surface of the supporting body is fixedly connected to a connecting flange for mounting casters.

[0015] Through the above technical solution, by connecting the upper end of the connecting cylinder to the ash discharge end of the electrostatic precipitator and the lower end to the carrying hopper in a detachable manner, the ash discharge channel is isolated from the external environment, effectively preventing the problem of secondary dust re-entrainment caused by the direct exposure of the dust discharge port to external air. At the same time, the baffle can be flexibly rotated and connected to the ash discharge channel through the rotating shaft and bearing seat. Part of the rotating shaft extends out of the connecting cylinder and is fixedly connected to the locking gear, which can cooperate with the locking unit set on the outer wall of the connecting cylinder to lock and fix the locking gear. This achieves the purpose of locking the baffle to be rotatably connected to the ash discharge channel. The locking unit allows the baffle to present different fixed postures such as horizontal sealing, tilting agitation, or vertical opening. Specifically, when it is necessary to clean the dust inside the carrying hopper, the baffle can be in a horizontal state, which can seal the ash discharge channel and minimize air leakage; tilting agitation can actively cut and agitate the dust to ensure smooth ash discharge; and vertical opening allows for unobstructed ash discharge. In summary, by using a baffle that can be locked and rotated within the ash discharge channel, at least three functions—sealing, preventing clogging and agitation, and ensuring smooth ash discharge—can be integrated into the connecting cylinder. This makes the entire ash discharge process controllable, continuous, and efficient, fundamentally solving the problems of air leakage and blockage in traditional ash hoppers.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] In a specific embodiment provided in this disclosure, a dust hopper device for collecting dust is provided, with reference to... Figures 1 to 7 As shown, the ash hopper device includes: a connecting cylinder 1, a shielding mechanism, and a carrying hopper 2. One end of the connecting cylinder 1 is connected to the ash discharge end of the electrostatic precipitator, and the other end is detachably connected to the carrying hopper 2. The carrying hopper 2 has a receiving cavity, which is connected to the ash discharge channel of the connecting cylinder 1. The shielding mechanism includes a baffle 3, a rotating shaft 4, a bearing seat 5, and a locking assembly. The rotating shaft 4 is fixedly connected to the baffle 3. The bearing seat 5 is disposed on the connecting cylinder 1 and connected to the bearing seat 5. The baffle 3 is disposed in the ash discharge channel. The locking assembly includes a locking gear 11 and a locking unit 6. Part of the rotating shaft 4 extends through the bearing seat 5 to the outside of the ash discharge channel and is fixedly connected to the locking gear 11. The locking unit 6 is disposed on the outer wall of the connecting cylinder 1 and is used to lock and fix the locking gear 11 so that the baffle 3 can be locked and rotatably connected to the ash discharge channel.

[0023] Through the above technical solution, by connecting the upper end of the connecting cylinder 1 to the ash discharge end of the electrostatic precipitator and the lower end to the carrying hopper 2 in a detachable manner, the ash discharge channel is isolated from the external environment, effectively preventing the problem of secondary dust re-entrainment caused by the direct exposure of the dust discharge port to external air. At the same time, the baffle 3 is flexibly rotatably connected to the ash discharge channel through the rotating shaft 4 and bearing seat 5. The locking gear 11, which is partially extended from the connecting cylinder 1 and fixedly connected, can cooperate with the locking unit 6 set on the outer wall of the connecting cylinder 1, thereby locking the gear. Gear 11 is locked in place, enabling the baffle 3 to be lockably rotatably connected to the ash discharge channel. The locking unit 6 allows the baffle 3 to maintain different fixed positions, such as horizontally closed, tilted agitation, or vertically open. Specifically, when cleaning dust from inside the hopper 2, the baffle 3 can be in a horizontal position, sealing the ash discharge channel to minimize air leakage; tilted agitation actively cuts and agitates the dust, ensuring smooth ash discharge; and vertical opening allows for unobstructed ash discharge. In summary, by locking the baffle 3 rotatably connected to the ash discharge channel, at least three functions—sealing, anti-clogging agitation, and smooth ash discharge—are integrated into the connecting cylinder 1, making the entire ash discharge process controllable, continuous, and efficient, fundamentally solving the problems of air leakage and blockage in traditional ash hoppers.

[0024] Regarding the baffle 3: When the baffle 3 is rotated to the horizontal position and locked, it can completely close the ash discharge channel, acting as a sealing gate to block the ash discharge channel; when it is rotated to a certain tilt angle and locked, it can effectively adjust the cross-sectional area of ​​the ash discharge channel to control the ash discharge flow rate; when the baffle 3 is continuously rotated, it can effectively agitate the dust adhering to the baffle 3 and the inner wall of the ash discharge channel, forcing it to fall into the receiving cavity of the bearing hopper 2; when it is necessary to control the ash discharge flow rate, the baffle 3 needs to be locked and fixed by the locking unit 6, so that the baffle 3 can be placed vertically in the ash discharge channel, so that it faces the falling dust with its smallest end face, so as not to obstruct the dust as much as possible, and to achieve unobstructed ash discharge of almost the entire diameter.

[0025] In some implementations, reference Figures 2 to 4As shown, the locking unit 6 includes a first locking plate 601, a second locking plate 602, a locking plate 603, a pull rod 604, a locking plug 605, and a locking spring 606. The first locking plate 601 and the second locking plate 602 are both fixed to the outer wall of the connecting cylinder 1. The locking plug 605 and the locking plate 603 are both fixed to the pull rod 604. Both the first locking plate 601 and the second locking plate 602 have through holes for the pull rod 604 to pass through. The locking plate 603 and the locking spring 606 are both located on the first locking plate 601. Between the first locking plate 601 and the second locking plate 602, a locking spring 606 is sleeved on the pull rod 604, and a locking plug 605 is provided with a locking slot corresponding to the tooth groove of the locking gear 11; specifically, by fixing the first locking plate 601 and the second locking plate 602 to the outer wall of the connecting cylinder 1, and providing a through hole for the pull rod 604, the pull rod 604 can be stably installed on the first locking plate 601 and the second locking plate 602, ensuring that the pull rod 604 can move accurately during reciprocating motion, that is, enabling the locking plug 604 to move accurately during reciprocating motion. The locking slot of the 5 precisely engages with the tooth groove of the locking gear 11; the locking spring 606 is sleeved on the pull rod 604 and located between the first locking plate 601 and the locking plate 603, so that the locking spring 606 is always in a pre-compressed or compressible state, and its elastic force continuously acts on the pull rod 604 through the locking plate 603, thereby pushing the locking plug 605 fixed to the end of the pull rod 604 to always have a tendency to move in the direction of the locking gear 11, so that the locking slot provided on the locking plug 605 can automatically lock without manual intervention. The locking plug 605 engages tightly with the tooth groove of the locking gear 11, thereby locking the locking gear 11 and ensuring that the baffle 3 can be locked at any angle. When it is necessary to adjust the angle of the baffle 3, the operator only needs to pull the lever 604 outward to overcome the elastic force of the locking spring 606, so that the locking plug 605 can be separated from the locking gear 11. At this time, the baffle 3 can be easily rotated to the desired new position. After releasing the lever 604, the locking plug 605 will automatically reset and re-engage with the gear 11 under the action of the spring force.

[0026] In some implementations, reference Figure 4 As shown, in order to make it easier for personnel to pull the lever 604, the locking unit 6 also includes a pull ring 607. The pull ring 607 is located at the end of the lever 604 away from the locking plug 605. Personnel can easily pull the lever 604 to move by pulling the pull ring 607.

[0027] In some implementations, reference Figures 2 to 4As shown, the locking unit 6 includes a limiting pin 7. Specifically, the pull rod 604 is designed to have two working positions: a locked state and a released state. The pull rod 604 is provided with an anti-shrinkage hole 6041, and the second locking plate 602 is provided with a first limiting plate and a second limiting plate. The pull rod 604 is located between the first and second limiting plates, and both the first and second limiting plates are provided with limiting holes corresponding to the anti-shrinkage hole. When it is necessary to adjust the angle of the baffle 3 and pull the pull rod 604 to the released state... The anti-shrinkage hole 6041 will be coaxially aligned with the limiting holes on the first and second limiting plates. At this time, the limiting pin 7 can be inserted to reliably fix the pull rod 604 in the release position, thereby freeing the operator's hands and allowing them to focus on rotating the baffle 3 for precise angle adjustment. When the adjustment is completed, simply pull out the limiting pin 7, and the pull rod 604 will automatically reset under the action of the locking spring 606, so that the locking plug 605 re-engages with the tooth groove of the locking gear 11, and quickly returns to the locked state.

[0028] For example, by using the limiting pin 7 to limit the position of the pull rod 604, the safety risks and operation interruptions that may be caused by the accidental retraction of the pull rod 604 due to operator negligence or spring force during the adjustment of the baffle 3 angle can be effectively prevented, thus ensuring the stability and controllability of the adjustment process.

[0029] In some implementations, reference Figures 2 to 4 As shown, the cross-section of the pull rod 604 is square, and the cross-section of the through hole is also square. That is, the square fit ensures that the circumferential freedom of the pull rod 604 is strictly restricted when it passes through the first locking plate 601 and the second locking plate 602, preventing it from rotating around its own axis. This ensures that the locking slot of the locking plug 605 fixed to the end of the pull rod 604 can always maintain the preset correct meshing angle with the tooth groove of the locking gear 11, avoiding the problems of misalignment between the locking slot and the tooth groove of the locking gear 11, failure to engage smoothly, or interference wear caused by accidental rotation of the pull rod 604.

[0030] In some implementations, reference Figure 5 As shown, the baffle 3 is provided with an mounting ring groove 301 for mounting the scraper. The mounting ring groove 301 enables the replaceable installation of the scraper. By embedding the scraper made of wear-resistant material into the mounting ring groove 301, the edge of the scraper protrudes slightly from the outer contour of the baffle 3. During the rotation of the baffle 3, the scraper can continuously scrape off the stubborn dust adhering to the inner wall of the ash discharge channel, effectively preventing the long-term accumulation and caking of dust on the inner wall of the ash discharge channel.

[0031] In some implementations, reference Figure 1 , Figure 5 and Figure 7As shown, a handle 12 is installed at the end of the rotating shaft 4 located outside the ash discharge channel. Specifically, the handle 12 provides the operator with a labor-saving and secure point of force application, enabling them to easily overcome dust resistance using the lever principle and drive the rotating shaft 4 and the baffle 3 fixed thereto to rotate precisely within the ash discharge channel. By rotating the handle 12, the operator can intuitively adjust the angle of the baffle 3, thereby achieving precise control over the opening of the ash discharge channel (horizontal closure, tilting agitation, or vertical opening).

[0032] In some implementations, reference Figure 1 , Figure 6 and Figure 7 As shown, the connecting cylinder 1 includes a connecting section 101 and a discharge section 102. A shielding mechanism is provided on the connecting section 101. The end of the discharge section 102 facing away from the connecting section 101 is detachably connected to a carrying hopper 2. From the connecting section 101 toward the discharge section 102, the cross-sectional area of ​​the discharge section 102 gradually increases. Specifically, the gradual increase in cross-sectional area makes the discharge space more spacious after the dust enters the discharge section 102 from the relatively small connecting section 101. This effectively reduces the falling resistance and flow velocity of dust particles and reduces the risk of dust blockage at the channel diameter change. At the same time, the discharge section 102 provides a more spacious entrance to the receiving cavity of the carrying hopper 2 connected to it, allowing the dust to fall into the hopper more gently and dispersedly. This avoids the dust from accumulating at the entrance of the carrying hopper 2 to form a conical pile, thereby optimizing the effective holding space of the carrying hopper 2 and increasing the dust loading capacity of a single cleaning.

[0033] In some implementations, reference Figure 1 , Figure 6 and Figure 7 As shown, the carrying hopper 2 includes a fixed abutment ring plate 201 and a carrying body 202. The end of the discharge section 102 opposite to the connecting section 101 is fixedly connected to a connector 8. The connector 8 has a connector groove 801 for the abutment ring plate 201 to be inserted. Specifically, the connector groove 801 enables the quick installation or disassembly of the carrying hopper 2. When cleaning dust, the operator only needs to align the abutment ring plate 201 of the carrying hopper 2 and insert it into the connector groove 801 of the connector 8 to complete the installation. The disassembly process is also simple and quick, which greatly improves the efficiency of the cleaning operation. At the same time, the circumferential constraint of the connector groove 801 on the abutment ring plate 201 ensures that the carrying hopper 2 is stable after connection and will not shake or shift.

[0034] In some implementations, reference Figure 6 and Figure 7As shown, the bottom surface of the connector 8 is provided with multiple fixing posts 9, each fixing post 9 having a screw hole communicating with the connector groove 801. Meanwhile, the abutment ring plate 201 is provided with an embedded ring groove 2011 for installing a rubber gasket. Specifically, when the abutment ring plate 201 is inserted into the connector groove 801, a bolt can be installed through the screw hole, so that the bolt extends into the connector groove 801 and abuts against the abutment ring plate 201. At the same time, the rubber gasket installed in the embedded ring groove 2011 is compressed between the abutment ring plate 201 and the bottom surface of the connector groove 801 under the action of the bolt tightening force, forming an elastic sealing layer, so that the gap between the abutment ring plate 201 and the bottom surface of the connector groove 801 is filled, preventing dust from overflowing from the gap into the dust exhaust channel.

[0035] In some implementations, reference Figure 1 and Figure 6 As shown, the bottom surface of the bearing body 202 is fixedly connected to a connecting flange 10 for mounting casters. The casters enable the bearing hopper 2, which is fully loaded with dust, to be moved easily and flexibly. Operators can directly transfer the bearing hopper 2 to the designated processing area without relying on heavy machinery or heavy manual handling, which greatly reduces labor intensity and improves the automation level and overall efficiency of dust removal operations.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
