Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of distributor technology, and more specifically, to a reducer distributor for boiler pulse ash injection. Background Technology

[0002] The speed reducer distributor is a crucial component in a boiler pulse ash injection system. It distributes the mixed gas to each group of pulse generators as needed, ensuring stable and reliable ash blowing by each group. However, current speed reducer distributors are prone to shaft breakage during use, and the output shaft frequently jams, easily causing damage to the speed reducer. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a reducer distributor for boiler pulse ash injection, which solves the technical problems in the related art where reducer distributors are prone to shaft breakage accidents during use, and the output shaft often jams, which easily causes damage to the reducer.

[0004] According to one aspect, at least one embodiment of this disclosure provides a reducer distributor for boiler pulse ash injection, comprising,

[0005] case,

[0006] A brass bushing, wherein the brass bushing is disposed within the housing;

[0007] A speed reducer is located outside the housing. The speed reducer has an output shaft. The end of the output shaft away from the speed reducer is inserted into the brass bushing and forms a rotational fit with the housing and the brass bushing.

[0008] A distribution plate is disposed on the output shaft and located inside the housing. The distribution plate is located on the side of the brass bushing facing the reducer, and a gap is left between the distribution plate and the inner wall of the housing.

[0009] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, a connecting sleeve is further included. The connecting sleeve is disposed between the housing and the reducer and is fitted around the output shaft.

[0010] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, the connecting sleeve and the housing are detachably connected, and the connecting sleeve and the reducer are detachably connected.

[0011] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, the plate at the end of the housing away from the reducer has an inlet ring groove, an inlet channel, and an exhaust channel. One side of the distribution plate contacts the plate at the end of the housing away from the reducer, and an inlet cavity is left between the other side of the distribution plate and the housing. The inlet ring groove is located around the brass bushing. One end of the inlet channel communicates with the outside, and the other end of the inlet channel communicates with the inlet ring groove. The distribution plate has an inlet port and an exhaust port. The inlet port is located between the axis of the distribution plate and the exhaust port. One end of the inlet port communicates with the inlet ring groove, and the other end of the inlet port communicates with the inlet cavity. One end of the exhaust port communicates with the inlet cavity. After the distribution plate rotates, the other end of the exhaust port is used to communicate with or separate from one end of the exhaust channel. The other end of the exhaust channel communicates with the outside. There are multiple exhaust channels, and all the exhaust channels are arranged around the axis of the housing.

[0012] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, the number of air inlets is multiple, and all the air inlets are arranged around the axis of the distribution plate.

[0013] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, the housing includes a barrel body and a barrel cover, the barrel cover and the barrel body are detachably connected, the brass bushing is disposed on the barrel body, the reducer is located outside the barrel cover, and the output shaft passes through the barrel cover and is inserted into the brass bushing.

[0014] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, the barrel cover has a positioning protrusion on the side facing the barrel body, the positioning protrusion is inserted into the barrel body, and a sealing gasket is also included, the sealing gasket is fitted around the positioning protrusion and overlaps with the barrel body.

[0015] For example, in at least one embodiment of this disclosure, a reducer distributor for boiler pulse ash injection includes an input shaft on the reducer, and further comprises:

[0016] A positioning box is disposed on the reducer and located around the input shaft;

[0017] A positioning plate is disposed around the input shaft and located inside the positioning box, and is used to connect to the motor.

[0018] For example, in a boiler pulse ash injection reducer distributor provided in at least one embodiment of this disclosure, the input shaft has an overlapping flange, the positioning plate overlaps with the overlapping flange, and a positioning nut is also included. The positioning nut is threadedly connected to the input shaft, and the positioning plate is clamped between the positioning nut and the overlapping flange.

[0019] For example, in at least one embodiment of this disclosure, a reducer distributor for boiler pulse ash injection further includes a backstop washer, which is fitted around the input shaft and located between the positioning nut and the overlapping flange to prevent the positioning nut from loosening.

[0020] The beneficial effects of the embodiments disclosed are as follows: the brass bushing is disposed inside the housing; the reducer is located outside the housing, the reducer has an output shaft, the end of the output shaft away from the reducer is inserted into the brass bushing, and forms a rotational fit with the housing and the brass bushing; the distribution plate is disposed on the output shaft and located inside the housing, the distribution plate is located on the side of the brass bushing facing the reducer, and a gap is left between the distribution plate and the inner wall of the housing.

[0021] In this disclosure, the brass bushing provides good support and guidance for the output shaft. A gap is left between the distribution disc and the inner wall of the housing to prevent the distribution disc from directly contacting the inner wall of the housing during rotation. This reduces the frictional resistance experienced by the output shaft during rotation, allowing the output shaft to rotate more smoothly. This reduces the probability of shaft breakage and the possibility of output shaft jamming, thereby reducing the chance of damage to the reducer. The distribution disc can rotate freely within the housing, thus stably and reliably distributing the mixed gas to each group of pulse generators, achieving effective soot blowing operation.

[0029] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0030] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0031] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0035] like Figures 1-4 The diagram illustrates a boiler pulse ash injection reducer distributor according to an embodiment of the present disclosure, comprising a housing 1, a brass bushing 2, a reducer 3, and a distribution disc 4. The brass bushing 2 is disposed inside the housing 1; the reducer 3 is located outside the housing 1 and has an output shaft 5. The end of the output shaft 5 away from the reducer 3 is inserted into the brass bushing 2 and forms a rotational fit with the housing 1 and the brass bushing 2; the distribution disc 4 is disposed on the output shaft 5 and is located inside the housing 1. The distribution disc 4 is located on the side of the brass bushing 2 facing the reducer 3, and a gap is left between the distribution disc 4 and the inner wall of the housing 1.

[0036] In this embodiment, the brass bushing 2 provides good support and guidance for the output shaft 5. A gap is left between the distribution disc 4 and the inner wall of the housing 1 to avoid direct contact between the distribution disc 4 and the inner wall of the housing 1 during rotation, thereby reducing the frictional resistance experienced by the output shaft 5 during rotation. This allows the output shaft 5 to rotate more smoothly, reducing the probability of shaft breakage and the possibility of the output shaft 5 jamming, thus reducing the chance of damage to the reducer 3. The distribution disc 4 can rotate freely within the housing 1, thereby stably and reliably distributing the mixed gas to each group of pulse generators and achieving effective soot blowing operation.

[0037] In some examples, a connecting sleeve 6 is also included, which is disposed between the housing 1 and the reducer 3 and is fitted around the output shaft 5.

[0038] For example, such as Figure 1 As shown, the connecting sleeve 6 serves to connect and protect the output shaft 5, providing a relatively closed environment for the output shaft 5. This prevents external impurities from entering the housing 1 and affecting the normal operation of the internal structure. At the same time, it can also buffer the radial force on the output shaft 5 to a certain extent, thereby enhancing the stability and sealing of the entire device structure, reducing the interference of external factors on the output shaft 5 and the internal structure, and improving the reliability and service life of the equipment.

[0039] In some examples, the connecting sleeve 6 is detachably connected to the housing 1, and the connecting sleeve 6 is detachably connected to the reducer 3.

[0040] For example, detachable connections allow for quick and easy separation of parts when the equipment needs maintenance, repair, or replacement, facilitating operation and greatly improving the maintainability and replaceability of the equipment, reducing downtime and lowering maintenance costs.

[0041] In some examples, the plate at the end of the housing 1 away from the reducer 3 has an intake ring groove 7, an intake channel 8, and an exhaust channel 9. One side of the distribution plate 4 contacts the plate at the end of the housing 1 away from the reducer 3, and the other side of the distribution plate 4 leaves an intake cavity 10 between itself and the housing 1. The intake ring groove 7 is located around the brass bushing 2. One end of the intake channel 8 is connected to the outside, and the other end of the intake channel 8 is connected to the intake ring groove 7. The distribution plate 4 has an intake port 11 and an exhaust port 12. The intake port 11 is located between the axis of the distribution plate 4 and the exhaust port 12. One end of the intake port 11 is connected to the intake ring groove 7, and the other end of the intake port 11 is connected to the intake cavity 10. One end of the exhaust port 12 is connected to the intake cavity 10. After the distribution plate 4 rotates, the other end of the exhaust port 12 is used to connect or separate from one end of the exhaust channel 9. The other end of the exhaust channel 9 is connected to the outside. There are multiple exhaust channels 9, and all the exhaust channels 9 are arranged around the axis of the housing 1.

[0042] For example, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, taking the distribution plate 4 located above the intake ring groove 7, intake channel 8, and exhaust channel 9 as an example, the upper surfaces of the intake ring groove 7, intake channel 8, and exhaust channel 9 are all in contact with the lower surface of the distribution plate 4. The intake chamber 10 is located above the distribution plate 4. The distance between the axis of the upper surface of the exhaust channel 9 and the axis of the distribution plate 4 is equal to the distance between the axis of the exhaust port 12 and the axis of the distribution plate 4. The intake port 11 and the intake channel 8 are always connected to the intake ring groove 7. The external mixed gas enters the intake ring groove 7 through the intake channel 8, and then enters the intake chamber 10 through the intake port 11. When the exhaust port 12 is connected to the upper end of a certain exhaust channel 9, the mixed gas in the intake chamber 10 can be discharged through the exhaust channel 9 and distributed to the corresponding group of pulse generators. This can realize the orderly distribution of the mixed gas, so that each group of pulse generators can stably obtain the mixed gas, providing a guarantee for effective soot blowing operation and improving the uniformity and effect of soot blowing.

[0043] In some examples, there are multiple air intakes 11, and all air intakes 11 are arranged around the axis of the distribution disk 4.

[0044] For example, such as Figure 4As shown, the multiple air inlets 11 work together to ensure that the air-fuel mixture in the air intake ring groove 7 enters the air intake chamber 10 more evenly, avoiding insufficient or excessive air intake in certain areas. This further improves the uniformity of air-fuel mixture distribution, ensuring a more uniform pressure and concentration distribution within the air intake chamber 10. Consequently, the air-fuel mixture discharged from the exhaust channel 9 becomes more stable, improving the stability and reliability of the pulse generator. In this disclosure, all air inlets 11 are evenly arranged around the axis of the distribution disk 4.

[0045] In some examples, the housing 1 includes a barrel body 1-1 and a barrel cover 1-2, with the barrel cover 1-2 being detachably connected to the barrel body 1-1. A brass bushing 2 is mounted on the barrel body 1-1, a reducer 3 is located outside the barrel cover 1-2, and an output shaft 5 passes through the barrel cover 1-2 and is inserted into the brass bushing 2.

[0046] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, this detachable connection facilitates the disassembly and maintenance of components inside the housing 1, while ensuring the stability and reliability of the output shaft 5 rotation, thereby improving the overall performance and maintainability of the equipment.

[0047] In some examples, the lid 1-2 has a positioning protrusion 13 on the side facing the body 1-1, the positioning protrusion 13 is inserted into the body 1-1, and also includes a sealing gasket 14, which is fitted around the positioning protrusion 13 and overlaps with the body 1-1.

[0048] For example, such as Figure 1 As shown, the positioning protrusion 13 on the lid 1-2 is inserted into the barrel body 1-1, serving a positioning function to ensure accurate installation of the lid 1-2 and the barrel body 1-1. The sealing gasket 14 is fitted around the positioning protrusion 13 and overlaps with the barrel body 1-1, effectively preventing leakage of the gas mixture from the connection between the lid 1-2 and the barrel body 1-1. This improves the sealing performance of the casing 1, avoids energy loss and environmental pollution caused by gas mixture leakage, and ensures stable internal pressure, which is beneficial for the normal distribution of the gas mixture and the normal operation of the pulse generator.

[0049] In some examples, the reducer 3 has an input shaft 15 and also includes a positioning box 16 and a positioning disk 17. The positioning box 16 is disposed on the reducer 3 and located outside the input shaft 15; the positioning disk 17 is disposed outside the input shaft 15 and located inside the positioning box 16 for connection to the motor.

[0050] For example, such as Figure 1As shown, the positioning box 16 provides a stable installation environment for the positioning plate 17, ensuring the accuracy and stability of the connection between the motor and the input shaft 15, making the connection between the motor and the reducer 3 more reliable, accurately transmitting the power of the motor to the input shaft 15, reducing deviations and losses in the power transmission process, and improving the transmission efficiency and stability of the equipment.

[0051] In some examples, the input shaft 15 has an overlap flange 18, a positioning disc 17 overlaps with the overlap flange 18, and a positioning nut 19 is also included, which is threaded to the input shaft 15, with the positioning disc 17 clamped between the positioning nut 19 and the overlap flange 18.

[0052] For example, such as Figure 1 As shown, the overlapping flange 18 on the input shaft 15 provides support for the positioning disk 17. The positioning nut 19 cooperates with the overlapping flange 18 to fix the positioning disk 17 on the input shaft 15. This ensures that the positioning disk 17 is fixed on the input shaft 15, preventing it from moving axially during operation, ensuring the stability of the connection between the motor and the reducer 3, and thus improving the reliability of the power transmission of the entire equipment.

[0053] In some examples, a backstop shim 20 is also included, which is fitted around the input shaft 15 and located between the positioning nut 19 and the overlapping flange 18 to prevent the positioning nut 19 from coming loose.

[0054] For example, such as Figure 1 and Figure 5 As shown, the anti-reverse washer 20 can improve the stability and reliability of the positioning plate 17 installation, prevent the positioning plate 17 from changing position due to the loosening of the positioning nut 19, thereby ensuring the stable connection between the motor and the reducer 3 and reducing the probability of equipment failure.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
