Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a dust collector ash hopper ash level measuring device. Background Technology

[0002] Coal-fired power plants generate a large amount of dust, and dust collectors are devices that collect this dust. When the dust level in the ash hopper at the bottom of the dust collector is too high, and the dust cannot be cleared in time, the dust removal efficiency will decrease. Furthermore, the excessively heavy dust may cause the bottom of the dust collector to collapse, leading to an accident and forcing the unit to operate at reduced load or even shut down. Due to the harsh operating conditions inside the dust collector, and the fact that the internal electric field and flow field both affect the flow of dust, real-time monitoring of the dust collector's ash level is a challenge.

[0003] Currently, many coal-fired power plants in my country have not yet implemented dust collector ash level measurement upgrades, leaving their ash level measurements in a "blind" mode, relying mainly on the experience of operators to accurately predict ash levels. With significant fluctuations in the types of coal blended in power plants and changes in equipment operating conditions, dust collector ash hopper overflow has become a problem for many power plants. Therefore, it is necessary to design a dust collector ash hopper ash level measurement device to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust collector ash hopper ash level measuring device to solve the problems mentioned in the background art.

[0005] This utility model discloses a dust collector ash hopper ash level measuring device, comprising a housing, with an air inlet pipe and an exhaust pipe respectively arranged on both sides of the housing, an ash hopper body arranged at the bottom of the housing, an ash discharge nozzle installed at the bottom of the ash hopper body, and support feet arranged at the four corners of the outer side of the housing. A drive assembly is arranged on the front of the ash hopper body, the drive assembly including a support plate, a drive mechanism, a limit rod, a threaded rod, a first sliding sleeve, a support rod, a second sliding sleeve, a connecting rod, and a bevel gear; a vibration assembly is arranged on one side of the first sliding sleeve, the vibration assembly including a first mounting plate, a rapping mechanism, a second mounting plate, striking steel balls, a locking rod, a movable cavity, and a spring; and a sensor is arranged on one side of the front of the ash hopper body.

[0006] As a further improvement of this utility model, there are two support plates, which are respectively arranged on the front of the ash hopper body near the top and bottom ends, and the two ends of the threaded rod are respectively connected between the two support plates by bearings.

[0007] As a further improvement of this utility model, the drive mechanism is installed on the front of the ash hopper body near one end of the threaded rod, and there are two bevel gears, which are respectively installed on the output shaft of the drive mechanism and the outer surface of the threaded rod, and the two bevel gears mesh with each other.

[0008] As a further improvement of this utility model, the first sliding sleeve is threaded onto the outer surface of the threaded rod, there are two support rods respectively disposed on the top of two support plates, the limiting rod is disposed between the two support rods, the second sliding sleeve is slidably disposed on the outer surface of the limiting rod, and the two ends of the connecting rod are respectively connected to the first sliding sleeve and the second sliding sleeve.

[0009] As a further improvement of this utility model, one side of the first mounting plate is connected and fixed to one side of the first sliding sleeve, and there are two movable cavities, which are respectively opened on the side of the first mounting plate away from the first sliding sleeve.

[0010] As a further improvement of this utility model, there are two locking rods, both of which are designed in a "7" shape. Both locking rods are connected to the side of the second mounting plate that is close to the first mounting plate and correspond to the position of the movable cavity.

[0011] As a further improvement of this utility model, the second mounting plate is designed with an L-shaped structure, the vibrating mechanism is installed on the top of the second mounting plate, the clamping rod is movably engaged in the movable cavity, the spring is set in the movable cavity and sleeved on the outer surface of the clamping rod, and there are several striking steel balls that are evenly distributed on the bottom end face of the second mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a vibrating mechanism in conjunction with striking steel balls and a sensor to enable the vibrating mechanism to strike the ash hopper body. The vibration frequency generated during the striking is transmitted to the spectrum analyzer through the sensor. The different striking frequencies fed back by the different amounts of ash inside the ash hopper body can be used to determine the amount of ash stored inside the ash hopper body, thereby effectively helping the staff to understand the degree of ash accumulation inside the ash hopper body in real time.

[0014] 2. Simultaneously, by utilizing the set movable cavity and spring, in conjunction with the locking rod, the vibrating mechanism can better drive the striking steel balls at the bottom of the second mounting plate to quickly strike the outer surface of the ash hopper body during vibration, resulting in a better striking effect. Furthermore, in conjunction with the drive mechanism and threaded rod, the striking position can be better adjusted, thereby helping workers to more accurately understand the degree of ash accumulation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0023] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] Please see Figure 1-3This utility model includes a box body 01, with an air inlet pipe 011 and an exhaust pipe 012 respectively on both sides of the box body 01. A ash hopper body 02 is provided at the bottom of the box body 01, and an ash discharge nozzle 022 is installed at the bottom of the ash hopper body 02. Support feet 021 are provided at the four corners of the outer side of the box body 01. A drive assembly is provided on the front of the ash hopper body 02. The drive assembly includes a support plate 03, a drive mechanism 031, a limit rod 032, a threaded rod 033, a first sliding sleeve 034, a support rod 035, a second sliding sleeve 036, a connecting rod 037, and a bevel gear 038. A vibration assembly is provided on one side of the first sliding sleeve 034. The vibration assembly includes a first mounting plate 04, a vibrating mechanism 041, a second mounting plate 042, a striking steel ball 043, a locking rod 044, a movable cavity 045, and a spring 046. A sensor 05 is provided on one side of the front of the ash hopper body 02.

[0025] The sensor 05 is fixedly installed on the front of the ash hopper body 02, and the plug on one side is connected to an external spectrum analyzer via a connecting cable, thereby transmitting the vibration signal generated during impact to the spectrum analyzer. This helps the staff to understand the amount of ash accumulated inside the ash hopper body 02 based on different spectrum fluctuations. The sensor 05 is a vibration sensor and its model number is "SW11533".

[0026] Please see Figure 1 and Figure 2 In this embodiment, in order to better strike different positions of the ash hopper body 02 and thus more accurately help the staff understand the amount of ash accumulated inside the ash hopper, there are two support plates 03, which are respectively set on the front of the ash hopper body 02 near the top and bottom. The two ends of the threaded rod 033 are respectively connected between the two support plates 03 through bearings. The support plates 03 and the ash hopper body 02 are fixed by welding.

[0027] The drive mechanism 031 is installed on the front of the ash hopper body 02 near one end of the threaded rod 033. There are two bevel gears 038, which are respectively installed on the output shaft of the drive mechanism 031 and the outer surface of the threaded rod 033, and the two bevel gears 038 mesh with each other.

[0028] The first sliding sleeve 034 is threaded onto the outer surface of the threaded rod 033. There are two support rods 035, which are respectively set on the top of the two support plates 03. The limiting rod 032 is set between the two support rods 035. The second sliding sleeve 036 is slidably sleeved on the outer surface of the limiting rod 032. The two ends of the connecting rod 037 are respectively connected to the first sliding sleeve 034 and the second sliding sleeve 036. The driving mechanism 031 is a stepper motor.

[0029] When it is necessary to drive the vibrating mechanism 041 to strike different positions of the ash hopper body 02, the drive mechanism 031 is activated. The forward and reverse rotation of the drive mechanism 031 and the bevel gear 038 drive the threaded rod 033 to rotate. This drives the first sliding sleeve 034 to move back and forth on the threaded rod 033 using the principle of the roller screw. This drives the vibrating mechanism 041 to strike different positions of the ash hopper body 02. When the first sliding sleeve 034 moves back and forth, the second sliding sleeve 036 will also move back and forth synchronously on the limit rod 032 under the action of the connecting rod 037, which will limit the first sliding sleeve 034.

[0030] Please see Figure 2 and Figure 3 It should be noted that, in order to better strike and vibrate the ash hopper body 02, thereby helping the staff to better understand the amount of ash accumulated inside the ash hopper body 02, one side of the first mounting plate 04 is connected and fixed to one side of the first sliding sleeve 034, and there are two movable cavities 045, which are respectively opened on the side of the first mounting plate 04 away from the first sliding sleeve 034.

[0031] There are two levers 044, both of which are designed in the shape of a "7". Both levers 044 are connected to the side of the second mounting plate 042 that is close to the first mounting plate 04 and correspond to the position of the movable cavity 045.

[0032] The second mounting plate 042 has an L-shaped structure design. The vibration mechanism 041 is installed at the top of the second mounting plate 042. The locking rod 044 is movably locked in the movable cavity 045. The spring 046 is set in the movable cavity 045 and sleeved on the outer surface of the locking rod 044. There are several striking steel balls 043, which are evenly distributed on the bottom surface of the second mounting plate 042. The vibration mechanism 041 is a vibration motor.

[0033] When it is necessary to detect the amount of ash inside the ash hopper body 02, the rapping mechanism 041 is activated. The vibration generated by the rapping mechanism 041 will cause the locking rod 044 to move up and down in the movable cavity 045 in conjunction with the spring 046, thereby causing the striking steel ball 043 at the bottom of the second mounting plate 042 to continuously strike the outer surface of the ash hopper body 02. At this time, the vibration generated by the striking will be transmitted to the sensor 05 attached to the outer surface of the ash hopper body 02, and the sensor 05 will transmit the frequency to the spectrum analyzer so that the staff can see it. The staff can use this spectrum to determine the amount of ash accumulated inside the ash hopper body 02.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
