Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for silo tops, specifically a dust removal device for powder silos. Background Technology

[0002] In modern industrial production, ore silos, as key facilities for storing and processing powdery materials, often generate large amounts of dust during their operation. This dust not only severely pollutes the production environment but also poses a potential threat to the health of operators and is detrimental to the long-term stable operation of production equipment. To reduce the harm caused by dust, dust removal equipment is often installed on the top of the ore silo. A search revealed that patent publication number CN221451998U discloses a high-efficiency silo top dust removal device, including a dust collector housing. A first door and a second door are rotatably arranged on the front side of the dust collector housing to form a sealed space. Several support frames are installed on the inner wall of the dust collector housing from left to right. Each support frame has a semi-enclosed structure with an opening on the front. Several support rods are equidistantly installed on the inner wall of each support frame from left to right.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] While existing dust removal equipment for powder silos can effectively remove dust, it suffers from the problem of being difficult for users to clean when the filter structure becomes clogged.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model proposes a dust removal device for powder silos, which solves the problem that although the existing dust removal devices for powder silos can play a role in dust removal, it is not convenient for users to clean them when the filter structure is clogged during actual use.

[0007] To achieve the above objectives, the basic technical solution proposed by this utility model is as follows:

[0008] A dust removal device for a powder silo includes a housing and an exhaust fan mounted on one side of the housing. A support mechanism is installed inside the housing, and a filter is installed inside the support mechanism. Rotary shafts are rotatably installed inside the housing on both sides of the top of the support mechanism. Several protrusions are installed at equal intervals on the rotating shafts. A motor corresponding to the position of the rotating shafts is installed at the front end of the housing.

[0009] A pulse dust removal mechanism is installed on the other side of the housing. The pulse dust removal mechanism includes an air tank, a pulse valve, and a jet pipe. The air tank is installed on the other side of the housing. A jet pipe extending into the housing is installed on the top of the air tank. A pulse valve is installed around the jet pipe. A control console is installed on the other side of the housing below the pulse dust removal mechanism. An air valve is installed at the front end of the housing.

[0010] Preferably, the pulse dust removal mechanism further includes a hanger and a drain valve, with the top of the jet pipe connected to the housing via the hanger, and the drain valve installed at the bottom of the air tank.

[0011] Preferably, the pulse dust removal mechanism further includes a mounting frame and a limiting ring. The mounting frame is fixedly installed on the other side of the housing, and the limiting ring is sleeved around the air tank. The bottom of the limiting ring is connected to the mounting frame.

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a dust removal device for a powder silo, including a housing 1 and an exhaust fan 10 mounted on one side of the housing 1. A support mechanism 8 is installed inside the housing 1, and a filter 9 is installed inside the support mechanism 8. A rotating shaft 6 is rotatably installed inside the housing 1 on both sides of the top of the support mechanism 8. Several protrusions 7 are installed at equal intervals on the rotating shaft 6. A motor 5 corresponding to the position of the rotating shaft 6 is installed at the front end of the housing 1. A pulse dust removal mechanism 2 is installed on the other side of the housing 1. The pulse dust removal mechanism 2 includes an air tank 201, a pulse valve 202, and a jet pipe 203. The air tank 201 is installed on the other side of the housing 1. A jet pipe 203 extending into the housing 1 is installed on the top of the air tank 201. A pulse valve 202 is installed around the jet pipe 203. A control console 3 is installed on the other side of the housing 1 below the pulse dust removal mechanism 2. An air valve 4 is installed at the front end of the housing 1.

[0026] Based on the above structural configuration, the dust removal equipment for the powder silo consists of a housing 1, a filter 9, and an exhaust fan 10. The housing 1 is mounted on the top of the powder silo, with an air inlet at the bottom. The filter 9 filters impurities in the gas, and the exhaust fan 10 extracts the gas from inside the housing 1, achieving gas filtration. Specifically, after the housing 1 is assembled, it is connected to an external power source via wires. After connection, the exhaust fan 10 is started, guiding the dust from inside the powder silo to the filter 9. The filter 9 filters the dust in the gas, and the filtered gas is discharged from the exhaust fan 10. After filtration, the exhaust fan 10 is turned off. The pulse dust removal mechanism 2 is controlled via the control panel 3. After opening the pulse valve 202, the gas in the air tank 201 is blown through the jet pipe 203 to clean the filter 9, thereby removing the dust adsorbed on the filter 9. During the cleaning process of the pulse dust removal mechanism 2, the motor 5 is started. After the motor 5 is powered on, it drives the rotating shaft 6 to rotate. During the rotation of the rotating shaft 6, the protrusion 7 squeezes the support mechanism 8. After the support mechanism 8 is under force, the mounting plate 802 drives the filter 9 to move up and down, improving the cleaning effect of dust on the filter 9. After connecting to the external pipeline by using the air valve 4, the air valve 4 is opened, and the exhaust fan 10 can guide the external gas into the box 1 for dust removal, expanding the application range of the device. This powder silo dust removal equipment is equipped with a pulse dust removal mechanism 2, a rotating shaft 6 and protrusion 7. During use, the pulse dust removal mechanism 2 performs reverse jet cleaning of the filter 9. The rotating shaft 6, driven by the motor 5, squeezes the support mechanism 8 with the protrusion 7, causing the support mechanism 8 to drive the filter 9 to vibrate at the same frequency, thereby improving the cleaning effect of dust on the filter 9.

[0027] Furthermore, the pulse dust removal mechanism 2 also includes a hanger 204 and a drain valve 205. The top of the jet pipe 203 is connected to the housing 1 via the hanger 204, and the drain valve 205 is installed at the bottom of the air tank 201. The hanger 204 is fitted around the jet pipe 203; specifically, the hanger 204 can limit the position of the jet pipe 203 inside the housing 1, and the drain valve 205 can drain any residual water inside the air tank 201.

[0028] Furthermore, the pulse dust removal mechanism 2 also includes a mounting frame 206 and a limiting ring 207. The mounting frame 206 is fixedly installed on the other side of the housing 1, and the limiting ring 207 is sleeved around the air tank 201, with its bottom connected to the mounting frame 206. The mounting frame 206 has a groove for installing the drain valve 205. Specifically, the mounting frame 206 and the limiting ring 207 can limit the position of the air tank 201 on the housing 1, making the air tank 201 more stable.

[0029] Furthermore, the support mechanism 8 includes an inner partition 801, a mounting plate 802, and a telescopic rod 803. The outer periphery of the inner partition 801 is fixedly connected to the inner wall of the housing 1, and the mounting plate 802 is mounted on top of the inner partition 801 via the telescopic rod 803. The inner partition 801 and the mounting plate 802 have slots for installing the filter 9. Specifically, the filter 9 is assembled inside the inner partition 801 and the mounting plate 802, thus dividing the internal space of the housing 1.

[0030] Furthermore, the support mechanism 8 also includes springs 804, and several springs 804 are installed on the top of the inner partition 801 between the telescopic rods 803. Specifically, the cooperation between the springs 804 and the telescopic rods 803 can support the mounting plate 802.

[0031] Furthermore, lifting rings 11 are fixedly installed on both sides of the top of the housing 1, and a protective cover 12 is installed on the top of the other side of the housing 1. Specifically, the lifting rings 11 facilitate the lifting and movement of the device by the user during use, and the protective cover 12 can shield and protect the exposed pulse dust removal mechanism 2.
