Description

Technical Field

[0001] This utility model relates to the field of ash transport device technology, and more specifically, to an ash transport device for dust removal equipment. Background Technology

[0002] In industrial production, dust collectors are widely used to collect and treat dust. The dust in their ash hoppers needs to be promptly transported to designated locations, such as raw material silos, by a dust conveying device to prevent accumulation and disruption of equipment operation. Currently, pneumatic dust conveying devices are widely used due to their high degree of automation and efficient conveying. For example, Chinese Patent Publication No. CN217731995U discloses a pneumatic dust conveying device for a dust collector, including a temporary ash storage silo, an ash inlet pipe, an air inlet pipe, a dust conveying pipe, and an automated dust conveying system. This device uses a controller to control the opening and closing of electric and solenoid valves to achieve automatic dust unloading and airflow conveying. Simultaneously, by installing motor-driven rotating stirring blades within the temporary ash storage silo, dust accumulation is prevented, thereby improving dust conveying efficiency.

[0003] However, the agitator in this device can only act on a localized area at the bottom of the ash storage silo. It is difficult for the agitator blades to reach the sticky dust and clumps of ash adhering to the silo walls. Long-term use can easily lead to dust accumulation on the silo walls, silo openings, and ash conveying pipe interfaces, gradually reducing the flow cross-section and eventually causing blockage of the ash conveying pipes. Furthermore, the agitator is a rigid rotating structure. If large particles of impurities are mixed in with the dust, it can easily cause the agitator blades to jam and the motor to overload. Utility Model Content

[0004] This utility model provides a dust removal equipment ash conveying device, which solves the defect of traditional agitators that are difficult to clean the deposits on the bin walls.

[0005] To achieve the above objectives, this utility model proposes a dust removal equipment ash transport device, which adopts the following technical solution:

[0006] A dust removal equipment ash transport device includes a support frame, a temporary ash storage bin, and two bin covers. Slip rings are fixedly connected to both ends of the temporary ash storage bin. Mounting sleeves are fixedly connected to the outer walls of both bin covers. The slip rings are located within and slidably connected to the mounting sleeves. Telescopic corrugated pipes are fixedly connected to both ends of the temporary ash storage bin, with the ends of the telescopic corrugated pipes fixedly connected to the bin covers. The temporary ash storage bin is fixedly connected to the support frame. A vertical vibration motor is fixedly connected to the top of the support frame, and the output end of the vertical vibration motor is fixedly connected to the temporary ash storage bin.

[0007] Through the above technical solution, the vertical vibration motor drives the temporary ash storage silo to vibrate as a whole, replacing the traditional rigid mixing structure. It can act on the entire area of ​​the ash storage silo, making it difficult for dust to accumulate on the silo walls, silo opening and ash conveying pipe interface.

[0008] Preferably, a plurality of second springs are fixedly connected to the outer circumference of the slip ring, and the other end of the second spring is fixedly connected to the inner wall of the mounting sleeve.

[0009] Through the above technical solution, the second spring provides elastic buffering for the vibration of the temporary ash storage silo, reduces the impact of vibration on the mounting sleeve and silo cover, and can extend the service life of the device. The second spring can enhance the vibration effect of the temporary ash storage silo, making it easier for dust to detach from the silo wall and further improve the anti-clogging effect.

[0010] Preferably, both ends of the slip ring are fixedly connected to sealing rings, and the sealing rings are slidably connected to the inner wall of the mounting sleeve.

[0011] By using the above technical solution, the sealing ring fills the gap between the slip ring and the mounting sleeve, which can reduce the friction between the slip ring and the mounting sleeve.

[0012] Preferably, the inner circumferential wall of the temporary ash storage silo is provided with a plurality of vibrating plates at equal intervals, and a first spring is fixedly connected to both ends of each vibrating plate, with the end of the first spring being fixedly connected to the inner wall of the temporary ash storage silo.

[0013] Through the above technical solution, the vibrating plate swings synchronously with the vibration of the ash storage silo, directly acting on the sticky dust and clumps attached to the silo wall, enhancing the local dust removal effect. The first spring assists the vibrating plate in generating a larger amplitude reciprocating motion, improving the ability to clean stubborn deposited dust and further reducing the risk of blockage.

[0014] Preferably, an ash hopper is fixedly connected to the top of the temporary ash storage silo, and an electric valve is fixedly connected to the discharge pipe of the ash hopper.

[0015] One of the compartment covers is fixedly connected to a connecting pipe at one end, and a filter and a solenoid valve are fixedly connected to the outer circumference of the connecting pipe.

[0016] A level gauge is fixedly connected to the top of the support frame. The detection end of the level gauge extends into the temporary ash storage silo. A rubber sheet is fixedly connected to the inner wall of the temporary ash storage silo. The level gauge passes through the rubber sheet and is fixedly connected to it.

[0017] Another ash conveying pipe is fixedly connected to the end of the silo cover.

[0018] With the above technical solution, the connecting pipe is connected to a positive pressure airflow source, namely a compressed air tank or air compressor. After the dust collector completes the dust removal operation, the controller opens the electric valve to start unloading the ash. The ash material enters the temporary ash storage silo. The level gauge senses the ash material entering. When the value of the level gauge is greater than the preset maximum value, the controller closes the electric valve and opens the solenoid valve to allow the positive pressure airflow to rush into the temporary ash storage silo, thereby sending the dust out from the ash conveying pipe. When the value of the level gauge is less than the preset minimum value, the controller closes the solenoid valve.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a vertical vibrating motor to drive the temporary ash storage silo to vibrate as a whole, the vibration energy is transmitted to the entire ash storage silo area, including the silo walls, silo opening, and ash conveying pipe interfaces, which are difficult for traditional agitators to reach. This prevents dust from accumulating in these key locations and solves the blockage problem caused by the reduced flow cross-section. At the same time, it can replace the traditional rigid rotating agitators. Even if large particles of impurities are mixed in with the dust, it will not cause the device to jam. It also avoids the risk of motor overload. The vibration can cause the sticky dust and clumps of ash adhering to the silo walls to be shaken off, solving the defect of traditional agitators in being unable to clean the silo wall deposits.

[0021] 2. The vibrating plate swings synchronously with the ash storage silo, directly acting on the sticky dust and clumps attached to the silo wall, enhancing the local dust removal effect. The first spring assists the vibrating plate in generating a larger amplitude reciprocating motion, improving the ability to clean stubborn deposited dust and further reducing the risk of clogging.

[0028] 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.

[0029] like Figures 1-5 As shown, a dust removal equipment ash transport device includes a support frame 9, a temporary ash storage bin 1, and two bin covers 4. Slip rings 16 are fixedly connected to both ends of the temporary ash storage bin 1. Mounting sleeves 15 are fixedly connected to the outer walls of the two bin covers 4. The slip rings 16 are located inside the mounting sleeves 15 and are slidably connected to them. Telescopic corrugated pipes 19 are fixedly connected to both ends of the temporary ash storage bin 1. The ends of the telescopic corrugated pipes 19 are fixedly connected to the bin covers 4. The temporary ash storage bin 1 is fixedly connected to the support frame 9. A vertical vibration motor 10 is fixedly connected to the top of the support frame 9. The output end of the vertical vibration motor 10 is fixedly connected to the temporary ash storage bin 1.

[0030] The vertical vibration motor 10 drives the temporary ash storage silo 1 to vibrate as a whole, replacing the traditional rigid mixing structure. It can act on the entire area of ​​the ash storage silo, making it difficult for dust to accumulate on the silo walls, silo opening and ash conveying pipe 5 interface.

[0031] like Figure 5 As shown, multiple second springs 17 are fixedly connected to the outer circumference of the slip ring 16, and the other end of the second spring 17 is fixedly connected to the inner wall of the mounting sleeve 15.

[0032] The second spring 17 provides elastic buffering for the vibration of the temporary ash storage bin 1, reducing the impact of vibration on the mounting sleeve 15 and bin cover 4, and extending the service life of the device. The second spring 17 can enhance the vibration effect of the temporary ash storage bin 1, making it easier for dust to detach from the bin wall and further improving the anti-clogging effect.

[0033] like Figure 5 As shown, sealing rings 18 are fixedly connected to both ends of the slip ring 16, and the sealing rings 18 are slidably connected to the inner wall of the mounting sleeve 15.

[0034] The sealing ring 18 fills the gap between the slip ring 16 and the mounting sleeve 15, which can reduce the friction between the slip ring 16 and the mounting sleeve 15.

[0035] like Figure 2 and Figure 4 As shown, the inner circumferential wall of the temporary ash storage silo 1 is provided with multiple vibrating plates 13 at equal intervals. Both ends of the vibrating plates 13 are fixedly connected to a first spring 14, and the ends of the first spring 14 are fixedly connected to the inner wall of the temporary ash storage silo 1.

[0036] The vibrating plate 13 swings synchronously with the vibration of the ash storage silo, directly acting on the sticky dust and clumps attached to the silo wall, enhancing the local dust removal effect. The first spring 14 assists the vibrating plate 13 to generate a larger amplitude reciprocating motion, improving the ability to clean stubborn deposited dust and further reducing the risk of blockage.

[0037] like Figure 1 As shown, a temporary ash storage silo 1 is fixedly connected to an ash hopper 2 at its top, and an electric valve 3 is fixedly connected to the discharge pipe of the ash hopper 2.

[0038] One of the compartment covers 4 has a connecting pipe 6 fixedly connected to its end, and a filter 7 and a solenoid valve 8 are fixedly connected to the outer circumference of the connecting pipe 6.

[0039] A level gauge 11 is fixedly connected to the top of the bracket 9. The detection end of the level gauge 11 extends into the temporary ash storage silo 1. A rubber sheet 12 is fixedly connected to the inner wall of the temporary ash storage silo 1. The level gauge 11 passes through the rubber sheet 12 and is fixedly connected to it.

[0040] Another silo cover 4 has a fixed connection at one end to a ash conveying pipe 5.

[0041] Connecting pipe 6 connects to a positive pressure airflow source, i.e., a compressed air tank or air compressor. After the dust collector completes the dust removal operation, the controller opens the electric valve 3 to begin unloading ash. The ash material enters the temporary ash storage silo 1, and the level gauge 11 senses the ash material entering. When the value of the level gauge 11 is greater than the preset maximum value, the controller closes the electric valve 3 and opens the solenoid valve 8, allowing positive pressure airflow to rush into the temporary ash storage silo 1, thereby sending the dust out through the ash conveying pipe 5. When the value of the level gauge 11 is less than the preset minimum value, the controller closes the solenoid valve 8. The control logic of the controller is existing technology, such as the CN217731995U patent mentioned in the background art, which will not be described in detail in this utility model.

[0042] The positive pressure airflow source is a compressed air tank or an air compressor. The compressed air will produce water vapor, which is filtered out by filter 7 to prevent dust from becoming damp and sticking to the inside of the device.

[0043] The implementation principle of this application is as follows: When in use, the connecting pipe 6 is connected to the positive pressure airflow source, i.e., the compressed air tank or air compressor. After the dust collector completes the dust removal operation, the controller opens the electric valve 3 to start unloading the ash. The ash material enters the temporary ash storage silo 1. The level gauge 11 senses the ash material entering. When the value of the level gauge 11 is greater than the preset maximum value, the controller closes the electric valve 3 and opens the solenoid valve 8 to allow the positive pressure airflow to rush into the temporary ash storage silo 1, thereby sending the dust out from the ash conveying pipe 5. When the value of the level gauge 11 is less than the preset minimum value, the controller closes the solenoid valve 8.

[0044] When the solenoid valve 8 is opened, the vertical vibration motor 10 is started. The ash storage bin vibrates within the mounting sleeve 15 through the slip ring 16. The second spring 17 extends and contracts synchronously with the vibration to buffer it. The vibrating plate 13 on the inner wall of the ash storage bin swings back and forth under the action of vibration. During the vibration process, the dust and clumps on the inner wall of the ash storage bin are dislodged from the bin wall by the vibration.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
