Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a mechanical and electrical integrated fan for a steelmaking plant. Background Art

[0002] Mechatronic fans are a new type of air power equipment that combines mechanical and electronic technologies to achieve intelligent control of fans. This technology uses advanced motor control technology and fan design theory to make the fan operation more stable, efficient and energy-saving. At the same time, mechatronic fans also have the advantages of intelligent control, automatic operation, remote monitoring, etc., and are suitable for air power needs in various fields.

[0003] The application number in the existing public technology is: CN202021720505.2. An integrated servo fan, which is provided with a positioning mechanism on the outside of the filter cover, drives the push rod to move to the right by pushing the push block, and the push rod drives the curved plate to rotate clockwise through the matching through hole. At the same time, the curved plate drives the sleeve and the card plate to move upward and disengage from the card slot on the outside of the fixed frame through the cylindrical matching groove. Then the fixed frame can be pulled outward and taken out, and the filter cover is pushed forward to drive the positioning block to disengage from the fixed frame and the inner side of the positioning slot, so as to quickly remove the filter cover that needs to be cleaned, thereby improving work efficiency and bringing convenient beneficial effects to work. CN202123339194.2. An electromechanical integrated fan solves the problem that a mixture of dust and moisture adheres to the fan blades during the operation of the current fan, thereby affecting the normal operating efficiency of the fan.

[0004] However, the above patent still has certain disadvantages when in use: although a positioning mechanism is provided to facilitate the disassembly of the filter cover, personnel still need to manually disassemble it, which is not only time-consuming and labor-intensive, but also increases the probability of contact between personnel's hands and fan blades, thereby increasing the risk of operation and the safety of operation is not very good. Moreover, when used inside a steel plant, due to the complex environment and high temperature of the steel plant, the temperature of the fan surface is easily high, and direct contact with personnel is very likely to cause burns. The overall use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a steel mill electromechanical integrated fan having the advantages of high maintenance safety, labor-saving dust removal operation, and self-replacement of the filter, thereby solving the problems in the above-mentioned background technology.

[0008] (II) Technical solution

[0009] To achieve the advantages of high maintenance safety, labor-saving dust removal operation, and self-replacement of the filter screen, the specific technical solution adopted by the present utility model is as follows:

[0010] An electromechanical integrated fan for a steel mill, comprising a housing and a base. One side surface of the housing is welded with an adjustment plate. An air inlet is formed through the contact position between the adjustment plate and the housing. One end of the air inlet is provided with a sealing groove inside the surface of the adjustment plate. Sealing pressure rings are symmetrically installed on both sides of the sealing groove. Electric push rods are symmetrically installed at both ends of the sealing pressure rings. A filter screen is arranged between the sealing pressure rings. Receiving and releasing grooves are symmetrically formed at both ends inside the adjustment plate. A driving shaft is installed at the middle position inside the receiving and releasing groove. One end of the driving shaft penetrates through one side of the adjustment plate and is connected to a first motor. A winding drum is fixedly installed on the surface of the driving shaft. The winding drum is wound and connected to the filter screen. A channel for the movement of the filter screen is formed inside the adjustment plate.

[0011] Furthermore, an impeller is arranged inside the housing. One end of the impeller penetrates through one side of the housing and is connected to a second motor.

[0012] Furthermore, an air outlet is formed at one side of the top of the housing.

[0013] Furthermore, the bottom of the housing is welded with a base. Positioning holes are symmetrically formed around the surface of the base.

[0014] Furthermore, a sealing gasket is arranged on the surface of the sealing pressure ring.

[0015] Furthermore, an electromechanical control device is arranged on one side of the housing.

[0016] Furthermore, a sealing door is installed on the surface of the adjustment plate at one side of the receiving and releasing groove.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present utility model provides an electromechanical integrated fan for a steel mill, which has the following beneficial effects:

[0019] The utility model adopts a winding drum and a sealing pressing ring. When a large amount of dust adheres to the surface of the filter screen after the fan has been used for a long time, the contraction of the electric push rod can drive the sealing pressing ring to move out from the surface of the filter screen. Then, through the relative release and winding operations of the two winding drums at both ends, the filter screen can be driven to move, so as to wind up the used filter screen below. The unused filter screen above can be moved back to the air inlet position. Then, through the return of the sealing pressing ring, the filter screen can be squeezed and fixed, and at the same time, the gaps outside the filter screen can be blocked to prevent dust from invading through the gaps. The whole replacement operation does not require much participation of personnel, can avoid scalding caused by the high temperature in the steel mill, and at the same time reduces the labor intensity of personnel. It has the advantages of high maintenance safety, labor-saving dust removal operation, and self-replacement of the filter screen. Brief Description of the Drawings

Detailed Embodiment

[0027] To further illustrate the embodiments, the present utility model provides accompanying drawings, which are part of the disclosure of the present utility model. These drawings are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present utility model, an electromechanical integrated fan for a steel mill is provided.

[0029] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners. As Figures 1-4 shown, an electromechanical integrated fan for a steel mill according to an embodiment of the present utility model includes a housing 1 and a base 5. A regulating plate 2 is welded to one side surface of the housing 1. An air inlet 9 is formed through the contact position between the regulating plate 2 and the housing 1. A sealing groove 7 is formed inside the surface of one end of the air inlet 9. Sealing pressure rings 6 are symmetrically installed on both sides of the sealing groove 7. Electric push rods 8 are symmetrically installed at both ends of the sealing pressure rings 6. A filter screen 14 is provided between the sealing pressure rings 6. Receiving and releasing grooves 13 are symmetrically formed at both ends inside the regulating plate 2. A driving shaft 11 is installed at the middle position inside the receiving and releasing grooves 13. One end of the driving shaft 11 penetrates through one side of the regulating plate 2 and is connected to a first motor 15. A winding drum 12 is fixedly installed on the surface of the driving shaft 11. The winding drum 12 is wound and connected to the filter screen 14. A channel for the movement of the filter screen 14 is formed inside the regulating plate 2.

[0030] In one embodiment, an impeller 3 is provided inside the housing 1. One end of the impeller 3 penetrates through one side of the housing 1 and is connected to a second motor 16. The impeller 3 is a basic component of the fan, so no further elaboration will be made here.

[0031] In one embodiment, an air outlet 10 is formed at one side of the top of the housing 1.

[0032] In one embodiment, a base 5 is welded to the bottom of the housing 1. Positioning holes 4 are symmetrically formed around the surface of the base 5. The positioning holes 4 are provided to facilitate the installation of the device at any designated position in the steel mill by personnel, facilitating subsequent use.

[0033] In one embodiment, a sealing gasket is provided on the surface of the sealing pressure ring 6. The sealing gasket is provided to improve the sealing performance of the sealing pressure ring 6 during use, prevent dust from invading through the gaps, and is made of a high-temperature resistant material to adapt to the high-temperature environment of the steel mill.

[0034] In one embodiment, an electromechanical control device is provided on one side of the housing 1. The electromechanical control device is a common component for electromechanical control and can be easily purchased on the market, so no further elaboration will be made here.

[0035] In one embodiment, a sealing door is installed on one side of the retractable slot 13 at the position on the surface of the adjustment plate 2. The sealing door is provided to facilitate the subsequent replacement and use of the winding drum 12 and the filter screen 14 by personnel.

[0036] Working principle: During actual use, personnel can flexibly install the device at any designated position in the steel mill through the base 5 and the positioning holes 4 on its surface, which is convenient for subsequent use. Since the components and technologies involved in mechatronic control are frequently used and the technology is mature in actual production and life, the corresponding structures are not marked and set in this application. Personnel can add them during the production stage, so no more details will be described here. When the device is used subsequently, the dust inside the steel mill can be blocked by the filter screen 14 on the surface of the air inlet 9, preventing the dust from invading the interior and damaging the impeller 3. After the filter screen 14 is used for a certain period of time, to prevent the adhesion of dust from clogging the holes and limiting the air intake, at this time, the retraction of the electric push rod 8 can drive the sealing pressure rings 6 on both sides to move outward synchronously. At this time, the first motors 15 on both sides can rotate simultaneously. The upper first motor 15 is in a release state, while the lower first motor 15 is in a winding state. In this way, the winding drum 12 at the connection between the two can be released and wound, so that the filter screen 14 between the two can be wound and replaced. By gathering the filter screen 14 attached with dust, the unused filter screen 14 can be pulled down. At this time, the new filter screen 14 can move to the position of the air inlet 9 again. Then, the reset of the electric push rod 8 can drive the sealing pressure ring 6 to clamp the filter screen 14, preventing the filter screen 14 from moving randomly, thereby ensuring its stability in subsequent use. When the device maintains the filter screen 14, it does not require manual operation by personnel, which can reduce the danger of operation, prevent burns caused by the high temperature inside the steel mill, and at the same time reduce the labor intensity of personnel, making the overall replacement process simple and fast. After multiple uses, only the winding drum 12 needs to be taken out and replaced, reducing the number of operations and making the overall use effect better. The device as a whole has the advantages of high maintenance safety, labor-saving dust removal operation, and self-replacement of the filter screen.
