Description

Technical Field

[0001] This application relates to the field of smoke coolers, and more particularly to a smoke cooler with a ash removal device. Background Technology

[0002] A flue gas cooler, also known as a flue gas cooler, is an industrial device that reduces the temperature of exhaust gases.

[0003] Currently, Chinese utility model patent CN204678932U discloses a rocker-arm cleaning plate cooler, comprising an upper housing and a lower housing. The upper and lower housings are separated into left and right sections by a partition. Multiple rows of cooling units are installed along the front-back direction in both left and right sections of the lower housing. Each row of cooling units has a cleaning chain on both sides. A cleaning chain drive mechanism is provided on the upper housing, including a rocker arm mechanism. The cleaning chain is mounted on the rocker arm mechanism, which drives the cleaning chain to swing back and forth, thereby cleaning the outer surface of the cooling units. This utility model has a good cleaning effect. The gear reducer drives the cleaning chain through a crank, connecting rod, rocker arm, and rocker arm mechanism. Since the rotational speed of the gear reducer remains constant, the angular velocity of the rocker arm mechanism is also constant. However, the effective cleaning direction of the cleaning chain is parallel to the direction of the cooling unit. The movement of the cleaning chain in the effective cleaning direction is not uniform. The removal of dust from the cooling unit requires time to overcome the adhesion force. If the contact time between the cleaning chain and the dust is too short, the adhesion between the dust and the surface of the cooling unit cannot be fully broken, and most of the dust will remain. If the contact time between the cleaning chain and the dust is too long, it will easily lead to low work efficiency. Utility Model Content

[0004] In order to improve working efficiency while effectively removing dust adhering to the cooling unit, this application provides a smoke cooler with a dust removal device.

[0005] This application provides a flue gas cooler with a dust removal device, which adopts the following technical solution: A smoke cooler with a dust removal device includes a housing, a partition, several cooling plates, two cleaning components, and a drive assembly. The partition is vertically arranged on the inner wall of the housing, and a gap exists between the partition and the bottom of the housing, connecting the smoke inlet and smoke outlet areas. The several cooling plates are vertically and parallelly arranged, distributed along a direction perpendicular to the smoke inlet and smoke outlet areas, and are located on the partition. The two cleaning components correspond to the smoke inlet and smoke outlet areas respectively, and each cleaning component includes several cleaning plates that abut against the side walls of the cooling plates. The drive assembly includes two main rods, a synchronous belt, two synchronous pulleys, and a drive motor. The two synchronous pulleys are distributed along a direction perpendicular to the cooling plates, and the synchronous belt is fitted onto the two synchronous pulleys. The drive motor drives one of the synchronous pulleys to rotate. The two main rods are slidably connected to the housing and threadedly connected to the synchronous belt. The several cleaning plates of the two cleaning components are respectively located on the two main rods.

[0006] By adopting the above technical solution, the main rod is driven to slide by the drive motor, synchronous pulley, and synchronous belt. The main rod drives the cleaning plate to move smoothly along the direction perpendicular to the distribution of the cooling plate. The cleaning plate abuts against the cooling plate and moves relative to the cooling plate in a straight line at a uniform speed, so as to achieve comprehensive cleaning of both sides of the cooling plate. The staff can change the moving speed of the cleaning plate according to the thickness of the dust, thereby improving work efficiency while effectively removing the dust attached to the cooling unit.

[0007] Optionally, the cleaning plate includes a cleaning rod and an abutment plate. The cleaning rod is vertically arranged, with one end of the cleaning rod attached to the main rod. The abutment plate is disposed on the cleaning rod and abuts against the surface of the cooling plate. The abutment plate is made of rubber.

[0008] By adopting the above technical solution, the elasticity and softness of the contact plate can make it fit tightly against the surface of the cooling plate, enhancing the scraping effect on the dust on the plate wall, while avoiding wear and tear on the cooling plate caused by hard materials. In addition, the cushioning properties of the rubber material can offset slight positional deviations during the cleaning process, ensuring that the cleaning plate and the cooling plate are always in effective contact, and improving the stability of dust removal.

[0009] Optionally, the cleaning plate further includes a rotating plate, the cleaning rod has a sliding groove in the vertical direction, the abutment plate is inserted into the cleaning rod through the sliding groove, the rotating plate is rotatably connected to the bottom of the cleaning rod, and the rotating plate is used to abut against the lower end face of the abutment plate.

[0010] By adopting the above technical solution, the abutment plate of the cleaning plate is inserted into the cleaning rod through the sliding groove, and the abutment plate is used to limit the contact of the lower end face of the abutment plate with the rotating plate, which realizes the quick disassembly and assembly of the abutment plate, which facilitates the subsequent replacement of worn cleaning parts and reduces the maintenance difficulty. The flexible rotation characteristics of the rotating plate not only ensure the stability of the abutment plate during operation, but also allow the abutment plate to be quickly released by flipping, without complicated disassembly steps, thus improving maintenance efficiency.

[0011] Optionally, a placement box is provided on the side wall of the box, the timing belt and timing pulley are located inside the placement box, the timing pulley is rotatably connected to the placement box, and the box has an adapter groove communicating with the placement box, and the timing belt is attached to the adapter groove.

[0012] By adopting the above technical solution, the synchronous belt and synchronous pulley are placed in the placement box on the side wall of the housing. The synchronous belt fits into the housing through the adapter groove, which not only avoids the wear and jamming caused by the synchronous belt and synchronous pulley being directly exposed to dusty flue gas, thus extending the service life of the drive components, but also ensures the stability of the synchronous belt drive and ensures the smooth operation of the cleaning components.

[0013] Optionally, an ash discharge pipe is provided at the bottom of the box, the bottom of the box is inclined, and a control valve is provided on the ash discharge pipe.

[0014] By adopting the above technical solution, an ash discharge pipe is installed at the bottom of the box with the bottom inclined. The cleaned and detached soot can automatically gather at the ash discharge pipe position under the action of gravity, avoiding the accumulation of soot in the box that affects the cooling efficiency or secondary adhesion to the cooling plate. The control valve on the ash discharge pipe can control the soot discharge as needed, which not only ensures the flexibility of operation, but also prevents the leakage of flue gas during the discharge process, and improves the environmental protection and safety of the equipment.

[0015] Optionally, the housing is provided with two operation boxes for easy replacement of the abutment plate. The two operation boxes are distributed along the sliding direction of the main rod. The operation boxes are set on the side wall of the housing and are connected to the interior of the housing. The bottom of the operation box is open and a sealing plate is provided at the bottom of the operation box to seal the bottom of the operation box.

[0016] By adopting the above technical solution, the two operating boxes on the housing are distributed along the sliding direction of the main rod and are connected to the inside of the housing. There is no need to disassemble the main body of the flue gas cooler. The contact plate can be directly contacted through the operating box, which solves the problem of complicated disassembly when replacing cleaning parts in existing equipment. In addition, the bottom opening of the operating box is set with a sealing plate, which can seal the housing to prevent flue gas leakage under normal circumstances. During maintenance, the sealing plate can be opened to operate, simplifying the maintenance process and reducing downtime for maintenance.

[0017] Optionally, the sealing plate is inclined and is used to guide the ash inside the operating box to the bottom of the box.

[0018] By adopting the above technical solution, the inclined sealing plate can guide the residual soot in the control box to the ash discharge channel at the bottom of the box, avoiding the accumulation of soot in the control box, reducing cleaning dead corners, and reducing the risk of failure caused by ash accumulation inside the equipment. At the same time, the inclined structure can achieve soot diversion without additional power. In conjunction with the inclined design at the bottom of the box, it improves the overall ash discharge efficiency and reduces the frequency of manual cleaning.

[0019] Optionally, the sealing plate is provided with a handle.

[0020] By adopting the above technical solution, a handle is provided on the sealing plate, which provides a convenient force application point for opening and closing the sealing plate, allowing the sealing plate to be opened or closed quickly without the aid of tools.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive assembly enables the main rod to move the cleaning plate at a constant speed along the distribution direction perpendicular to the cooling plate, and the smoke inlet area and smoke outlet area each correspond to a set of cleaning components to achieve synchronous dust removal on both sides; 2. The abutment plate is inserted into the cleaning rod through the sliding groove, and the rotating plate is rotatably connected to the bottom of the cleaning rod and abuts against the lower end face of the abutment plate, which can realize quick disassembly and assembly of the abutment plate and facilitate the replacement of worn parts; 3. The rod body, block body and belt body of the main rod form a synchronous belt structure. The belt body can seal the adapter groove connecting the box and the placement box, which can not only prevent the flue gas from leaking from the gap, but also prevent the soot from entering the interior of the placement box and causing the screw and other transmission components to jam, thus ensuring the long-term stable operation of the drive assembly.

[0033] The implementation principle of a smoke cooler with a dust removal device in this application embodiment is as follows: the partition 2 divides the box 1 into a smoke inlet zone 11 and a smoke outlet zone 12. The smoke flows through the smoke inlet 13, the smoke inlet zone 11, the bottom gap, the smoke outlet zone 12, and the smoke outlet 14. The two sets of cooling plates 3 are set in two separate zones and are in full contact with the smoke. The cooling medium introduced by the air inlet and the air outlet 19 completes the heat exchange and realizes the cooling of the smoke. The bottom of the box 1 has an inverted conical inclined structure to prepare for dust collection.

[0034] The drive motor 54 drives the synchronous pulley 53 inside the placement box 6 to rotate, and the synchronous belt 52 drives the main rod 51 and the cleaning plate 41 to move at a constant speed along the cooling plate 3; the rubber abutment plate 412 adheres to the cooling plate 3 to wipe away the dust, and the cleaned dust is collected along the inclined bottom of the box to be discharged through the ash outlet pipe 15, thus taking into account both the dust removal effect and the protection of the cooling plate 3.

[0035] When the abutment plate 412 needs to be replaced, the drive assembly 5 moves the cleaning plate 41 into the operation box 7. The operator holds the handle 81 to open the sealing plate 8 and rotates the bottom rotating plate 413 of the cleaning rod 411 to remove the abutment plate 412 from the sliding groove 414. The tilted sealing plate 8 can guide the ash back into the box 1. The entire process does not require disassembling the box 1, making maintenance convenient.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
