Description

Technical Field

[0001] This utility model relates to the field of cleaning water film dust collectors, and in particular to a device for cleaning accumulated dust in water film dust collectors. Background Technology

[0002] Water film dust collectors primarily utilize the close contact between a water film and dust-laden flue gas to transfer dust particles from the gas phase to the liquid phase, thereby achieving the effect of flue gas dust removal. A common type of water film dust collector is the cyclone water film dust collector. However, after prolonged use, ash and scale tend to accumulate and harden in the ash hopper of cyclone water film dust collectors, typically requiring manual cleaning during shutdown, which is quite troublesome. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a water film dust collector ash cleaning device, which facilitates and quickly cleans the ash deposits in the ash hopper, saving time and effort.

[0004] The technical solution of this utility model is as follows:

[0005] A dust removal device for a water film dust collector, comprising:

[0006] The support frame is located at the top of the inner side of the ash hopper;

[0007] The rotating mechanism is mounted on the support frame;

[0008] The cleaning structure includes a connecting frame, a first scraper and a second scraper. The first scraper and the second scraper are evenly arranged on the connecting frame in a circumferential direction and are parallel to the inclined inner wall of the ash hopper. The first scraper is provided with scraper teeth on one side in the forward direction, and the second scraper is provided with scraper blades on one side in the forward direction, which can fit against the inclined inner wall of the ash hopper.

[0009] In a further technical solution, the first scraping element comprises two, and the scraping teeth of the two first scraping elements are arranged alternately.

[0010] In a further technical solution, the support frame includes a support platform and a support rod. The support platform has a through hole in the middle, and the support rod is arranged around the edge of the support platform. The end of the support rod is connected to the inner wall of the ash hopper.

[0011] In a further technical solution, the rotating mechanism includes a motor, a reducer, a rotating shaft, and a waterproof shell. The motor is connected to the reducer and is located on the top of the support platform. The rotating shaft is connected to the reducer, and its end rotates through a through hole to connect with the connecting frame. The waterproof shell is fitted over the outside of the motor and the reducer, and its bottom edge is sealed to the support platform.

[0012] In a further technical solution, one side of the waterproof shell is provided with a sleeve extending through the side wall of the ash hopper for the motor cable to pass through.

[0013] In a further technical solution, the connecting frame includes a connecting sleeve, a first connecting rod, and a second connecting rod. The connecting sleeve is sleeved on the outside of the rotating shaft. The two ends of the first connecting rod are respectively connected to the connecting sleeve and the first scraper, and the two ends of the second connecting rod are respectively connected to the connecting sleeve and the second scraper.

[0014] In a further technical solution, the cleaning structure also includes a spray pipe, which includes an input pipe extending to the outside of the ash hopper and multiple nozzles.

[0015] In a further technical solution, the ash hopper is located at the bottom of the support frame and has a support ring on the inner wall of the first scraper and the second scraper. The spray pipe is annular and is mounted on the support ring. The spray nozzle is set towards the inclined inner wall of the ash hopper.

[0016] The beneficial effects of this utility model are:

[0017] 1. The rotating mechanism is mounted inside the ash hopper via a support frame. This position is lower than the flue gas inlet of the water film dust collector. Without affecting the use of the water film dust collector, it drives the first and second scraper components of the cleaning structure to clean the hardened ash on the inner wall of the ash hopper. During cleaning, the scraper teeth are mainly responsible for breaking the loose and harder ash. The scraper blades of the second scraper then push the ash down, which helps the broken ash fall to the bottom of the ash hopper under the action of gravity, making it easy to discharge and saving manpower to a great extent.

[0018] 2. The spray pipe can spray water to rinse the ash hopper. Harder ash can be softened by spraying and soaking, which will further facilitate the scraping work of the first and second scrapers. After scraping, water can be sprayed to rinse the ash residue remaining on the inner wall of the ash hopper. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Example:

[0025] like Figures 1-2 As shown, a dust removal device for a water film dust collector includes a support frame, a rotating mechanism, and a cleaning structure disposed within a dust hopper 10. The support frame is located at the top inner side of the dust hopper 10 and includes a support platform 21 and a support rod 22. The support platform 21 has a through hole in its center, and the support rod 22 surrounds the support platform 21 at its edge, with its end connected to the inner wall of the dust hopper 10. The rotating mechanism includes a motor 31, a reducer 32, a rotating shaft 33, and a waterproof shell 34. The motor 31 is connected to the reducer 32 and is located at the top of the support platform 21. The rotating shaft 33 is connected to the reducer 32, and its end extends through the through hole to the bottom of the support platform 21. The waterproof shell 34 is fitted over the motor 31 and the reducer 32, and a sealing strip can be provided at its bottom edge. The support platform 21 is connected by bolts to achieve a seal. The cleaning structure includes a connecting frame, a first scraper 41, and a second scraper 51. The components 51 are evenly arranged on the connecting frame around the perimeter and are parallel to the inclined inner wall of the ash hopper 10. The connecting frame includes a connecting sleeve 61, a first connecting rod 62, and a second connecting rod 63. Preferably, there are two connecting sleeves 61, one on top of the other, which are respectively fitted onto the outside of the rotating shaft 33. The two ends of the first connecting rod 62 are respectively connected to the connecting sleeve 61 and the first scraper 41. The two ends of the second connecting rod 63 are respectively connected to the connecting sleeve 61 and the second scraper 51. The first scraper 41 and the second scraper 51 can be connected to the connecting rod by bolts, which is convenient for easy disassembly and cleaning. The first scraper 41 has scraper teeth 42 on one side in the forward direction. The gap between the scraper teeth 42 and the inner wall of the ash hopper 10 can be 1-1.5mm. The first scraper 41 can include two, and the scraper teeth 42 of the two first scraper 41 are staggered. The second scraper 51 has a scraper blade 52 on one side in the forward direction, which can fit against the inclined inner wall of the ash hopper 10. The scraper blade 52 can be made of polyurethane.

[0026] In this embodiment, to improve the crushing efficiency of caking ash, a bin wall vibrator can also be installed on the outside of the ash hopper 10.

[0027] The working principle of the above technical solution is as follows:

[0028] When the ash hopper 10 needs to be cleaned, the starting motor 31 drives the rotating shaft 33 to rotate after being reduced in speed by the reducer 32. This causes the first scraper 41 and the second scraper 51 on the connecting frame to rotate. As the first scraper 41 rotates along the inclined inner wall of the ash hopper 10, the scraper teeth 42 squeeze and break the harder ash. The two first scraper 41 with staggered scraper teeth 42 can scrape and break the ash. The scraper blades 52 of the second scraper 51 then push the ash down. The broken ash falls to the bottom of the ash hopper 10 under the action of gravity, making it easy to discharge and saving manpower to a great extent.

[0029] In another embodiment, such as Figure 1 As shown, a sleeve 35 extending through the side wall of the ash hopper 10 is provided on one side of the waterproof shell 34 for the motor 31 cable to pass through.

[0030] The sleeve 35 can protect the motor 31 cable and reduce the failure rate.

[0031] In another embodiment, such as Figure 1 As shown, the cleaning structure also includes a spray pipe 71, which includes an input pipe 72 extending to the outside of the ash hopper 10 and multiple nozzles 73. The ash hopper 10 is located at the bottom of the support frame and is provided with a support ring 11 on the inner wall of the first scraper 41 and the second scraper 51. The spray pipe 71 is annular and is placed on the support ring 11. The nozzles 73 are arranged facing the inclined inner wall of the ash hopper 10.

[0032] The entire process of cleaning the spray pipe 71 can be connected to a water source through the input pipe 72 to rinse the ash hopper 10. Harder ash can be softened by spraying and soaking, which further facilitates the scraping work of the first scraper 41 and the second scraper 51. After scraping, water can be sprayed to rinse the ash residue remaining on the inner wall of the ash hopper 10.

[0033] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
