Description

Technical Field

[0001] This utility model relates to a cleaning device for a high-pressure blower of an industrial furnace. Background Technology

[0002] A high-pressure blower is a machine that uses input mechanical energy to increase gas pressure and discharge gas; it is a type of driven fluid machinery. High-pressure blowers are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling; in boilers and industrial furnaces for ventilation and induced draft; in air conditioning equipment and household appliances for cooling and ventilation; in grain drying and conveying; and as a wind source for wind tunnels and for inflating and propelling hovercraft. When high-pressure blowers are used in industrial furnaces, ventilation ducts are often connected to the blower's outlet. Welding slag inside these ducts can fall into the blower. If the slag is not cleaned promptly, it can cause wear on the blower's impeller, affecting its dynamic balance. Furthermore, after prolonged use, a thick layer of dust accumulates on the outer surface of the impeller, which also affects its dynamic balance and reduces the blower's efficiency. Therefore, a cleaning device for high-pressure blowers is urgently needed. Utility Model Content

[0021] Example

[0022] Reference Figures 1-4 This embodiment provides a cleaning device for a high-pressure blower in an industrial furnace. The high-pressure blower includes a fixed frame 1, a housing 2, an impeller 3, and a motor 4. The housing 2 is mounted on the fixed frame 1, the impeller 3 is mounted inside the housing 2, and the motor 4 is mounted on the fixed frame 1. The output end of the motor 4 extends into the housing 2 and connects to the impeller 3. The cleaning device includes a slag discharge assembly 5 and a dust removal assembly 6. The slag discharge assembly 5 is located at the bottom of the housing 2 and is used to remove welding slag that falls into the housing 2. The dust removal assembly 6 is located on the slag discharge assembly 5 and is used to clean the dust accumulated on the impeller 3.

[0023] A high-pressure blower generally consists of a fixed frame 1, a casing 2, an impeller 3, and a motor 4. The casing 2 is fixedly installed on the left side of the fixed frame 1. The impeller 3 is rotatably installed inside the casing 2. The motor 4 is fixedly installed on the top of the fixed frame 1, and the output end of the motor 4 extends into the casing 2 and is fixedly connected to the impeller 3. The motor 4 can drive the impeller 3 to rotate at high speed. In this embodiment, a slag discharge assembly 5 is added to the bottom of the casing 2 to clean the welding slag that falls from the duct into the casing 2 during the installation of the ventilation duct. A dust removal assembly 6 is installed on the slag discharge assembly 5. The device can periodically clean the dust accumulated on the outer surface of the impeller 3, thereby achieving timely cleaning of welding slag inside the casing 2 of the high-pressure blower and dust on the impeller 3. This prevents welding slag and dust from affecting the dynamic balance of the impeller 3 and ensures the working efficiency of the high-pressure blower. In addition, during the operation of the high-pressure blower, condensate will be generated inside the casing 2 due to the temperature difference between the inside and outside. In this embodiment, the condensate generated inside the casing 2 can also be discharged in time through the dust removal component 6 to prevent the condensate inside the casing 2 from corroding the inner wall of the casing 2 due to the inability to be discharged for a long time.

[0024] Specifically, the slag discharge assembly 5 includes a slot 51, a hinge 52, a sealing plate 53, and a plug 54. The slot 51 is located at the bottom of the housing 2. One end of the sealing plate 53 is rotatably mounted on one side of the slot 51 via the hinge 52, and the other end of the sealing plate 53 is fixedly mounted on the other side of the slot 51 via the plug 54.

[0025] The slag removal assembly 5 in this embodiment mainly consists of a slot 51, a hinge 52, a sealing plate 53, and a plug 54. A slot 51 is provided at the bottom of the housing 2 so that workers can clean the welding slag that falls into the bottom of the housing 2 through the slot 51. A hinge 52 is fixedly installed on the outer surface of the housing 2 on the left side of the slot 51. A sealing plate 53 is fixedly installed on the hinge 52. That is, the sealing plate 53 is installed on the left side of the slot 51 by rotating through the hinge 52, so that the sealing plate 53 can seal the slot 51 and ensure the normal operation of the high-pressure blower. A plug 54 is fixedly installed at the end of the sealing plate 53 away from the hinge 52. A through hole 21 is provided on the housing 2 to cooperate with the plug 54. By inserting the plug 54 into the through hole 21, the sealing plate 53 can be fixedly installed on the outer surface of the housing 2. The structure is simple and the operation is convenient.

[0026] Specifically, the dust removal assembly 6 includes a three-way ball valve 61, a water inlet pipe 62, and a drain pipe 63. The three-way ball valve 61 is mounted on the sealing plate 53. The first port 611 of the three-way ball valve 61 is connected to the inside of the housing 2. The water inlet pipe 62 is mounted on the second port 612 of the three-way ball valve 61, and the drain pipe 63 is mounted on the third port 613 of the three-way ball valve 61.

[0027] The dust removal assembly 6 in this embodiment mainly consists of a three-way ball valve 61, a water inlet pipe 62, and a drain pipe 63. The three-way ball valve 61 is fixedly installed on the bottom outer surface of the sealing plate 53. The first port 611 of the three-way ball valve 61 is connected to the inside of the housing 2. The water inlet pipe 62 is installed on the second port 612 of the three-way ball valve 61, so that external water can enter the inside of the housing 2 through the water inlet pipe 62, the second port 612 of the three-way ball valve 61, and the first port 611, so as to clean the dust accumulated on the impeller 3 at regular intervals. The drain pipe 63 is installed on the third port 613 of the three-way ball valve 61 so as to drain the sewage after cleaning the impeller 3 and the condensate generated by the temperature difference inside the housing 2.

[0028] Furthermore, a sealing gasket 7 is provided on the inner side of the sealing plate 53.

[0029] In this embodiment, a sealing gasket 7 is installed on the inner side of the sealing plate 53. By adding a sealing gasket 7 between the sealing plate 53 and the outer surface of the housing 2, the sealing performance between the sealing plate 53 and the groove 51 is increased. This not only prevents sewage from flowing out directly through the gap between the sealing plate 53 and the housing 2 during the cleaning of the impeller 3, but also ensures the overall sealing performance of the housing 2, thus ensuring the normal operation of the high-pressure blower.

[0030] Furthermore, a rubber pad 8 is provided on the top of the plug 54.

[0031] In this embodiment, a rubber pad 8 is installed on the top of the plug 54 to provide a certain sealing effect. When the plug 54 is inserted into the corresponding through hole 21 of the housing 2, part of the rubber pad 8 on the top of the plug 54 will extend into the interior of the housing 2. When the plug 54 retracts, the top of the plug 54 will squeeze the rubber pad 8, and the rubber pad 8 will deform to seal the gap between the top of the plug 54 and the through hole 21, so as to ensure the overall sealing of the housing 2. In addition, a sealing gasket 7 is also installed between the sealing plate 53 and the housing 2. The plug 54 penetrates the sealing gasket 7 to ensure the sealing between the bottom of the plug 54 and the through hole 21, thereby achieving a double-layer seal for the through hole 21 on the housing 2, further ensuring the overall sealing of the housing 2.

[0032] Furthermore, the bottom of the plug 54 has a circular ring structure.

[0033] In this embodiment, by setting the bottom of the plug 54 as a circular structure, it is not only convenient for the staff to insert the plug 54 into the through hole 21 of the housing 2, but also convenient to pull the plug 54 out of the through hole 21.

[0034] When installing ventilation ducts at the outlet of the high-pressure blower, residual welding slag inside the duct will fall down to the bottom of the casing 2 of the high-pressure blower. At this time, the operator can pull out the plug 54 to open the sealing plate 53 and clean out the welding slag inside the casing 2 through the slot 51. This prevents the welding slag from causing wear on the impeller 3 of the high-pressure blower and affecting the dynamic balance of the impeller 3, thus ensuring the working efficiency of the blower. After cleaning the welding slag, the plug 54 is reinserted into the through hole 21 of the casing 2.

[0035] After the high-pressure blower has been used for a period of time, the operator can rotate the handle 614 of the three-way ball valve 61 to connect the first port 611 and the second port 612 of the three-way ball valve 61. External water enters the casing 2 through the inlet pipe 62 via the second port 612 and the first port 611 of the three-way ball valve 61. After a certain amount of water is delivered, the three-way ball valve 61 is closed. At this time, the first port 611, the second port 612, and the third port 613 are no longer connected to each other. Then, the blower is started, and the impeller 3 agitates the inside of the casing 2. Water is used to thoroughly clean the dust accumulated on the outer surface of the impeller 3. After cleaning the impeller 3, the fan is turned off and the three-way ball valve 61 is opened. At this time, the first port 611 and the third port 613 of the three-way ball valve 61 are connected to each other. The sewage in the casing 2 flows into the drain pipe 63 through the first port 611 and the third port 613 and is finally discharged through the drain pipe 63. This achieves regular cleaning of the impeller 3, avoids the accumulation of a large amount of dust on the outer surface of the impeller 3, which affects the dynamic balance of the impeller 3, and ensures the working efficiency of the high-pressure fan.

[0036] Meanwhile, during the operation of the high-pressure blower, condensation will also occur inside the casing 2 due to the temperature difference between the inside and outside. At this time, the first port 611 and the third port 613 of the three-way ball valve 61 can be connected by rotating the handle 614 of the three-way ball valve 61, so as to discharge the condensation inside the casing 2 in time and avoid corrosion of the inner wall of the casing 2 due to the condensation not being discharged for a long time. It should be noted that the impeller 3 needs to be cleaned regularly in this embodiment to avoid the three-way ball valve 61 and the drain pipe 63 being blocked due to excessive dust in the sewage. If the three-way ball valve 61 is blocked or damaged, the plug 54 can be pulled out and the sealing plate 53 can be opened to repair and replace the three-way ball valve 61.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
