Description

Technical Field

[0001] The present application relates to the technical field of blowers, and in particular to a high-efficiency blower. Background Art

[0002] A blower is a device that compresses and transports gas through mechanical energy. Its outlet pressure range is typically 0.015 MPa to 0.35 MPa (1500 Pa to 35000 Pa). It is a general industrial equipment. Its core principle is to perform work on the gas through impeller rotation or volume change, so that the gas gains energy (pressure and speed), ultimately achieving gas transportation. It is widely used in gas power provision scenarios.

[0003] A high-efficiency blower refers to a type of blower that, under the same operating conditions (wind pressure and air volume), consumes less energy and has higher operating efficiency than traditional blowers. It also usually has additional advantages such as strong stability, low noise, and intelligence. With the advancement of energy-saving policies and the demand for industrial cost reduction, high-efficiency blowers have gradually replaced traditional models (such as some Roots blowers and low-end centrifugal blowers) and are widely used in sewage treatment, pneumatic conveying, new energy and other fields.

[0004] The air outlet position of some existing high-efficiency blowers can be adjusted. After the air outlet position is adjusted many times over a long period of time, the position of the adjustment structure is prone to loosening. At this time, the frequency of vibration of the high-efficiency blower body is easily increased during use, thereby accelerating the loosening speed of the bolts, and easily causing the motor installed by the bolts to loosen, affecting the use effect of the high-efficiency blower. Therefore, it is necessary to propose a high-efficiency blower to solve the above problems. Summary of the Invention

[0005] In order to solve the problem that the position of the adjustment structure of the existing high-efficiency blower is prone to loosening after the air outlet position is adjusted many times over a long period of time, which is easy to increase the frequency of the vibration of the high-efficiency blower body during use, thereby accelerating the speed of the bolt loosening, and easily causing the motor installed by the bolts to loosen, affecting the use effect of the high-efficiency blower, the present application provides a high-efficiency blower.

[0006] This application provides a high-efficiency blower, which adopts the following technical solution: A high-efficiency blower includes a fixed frame, a rotating drum is rotatably mounted on the inner side of the fixed frame, a mounting plate is fixedly mounted inside the rotating drum, a motor is connected to the rear side of the mounting plate by bolts, a rotating rod is fixedly mounted on the front side of the motor, the front side of the rotating rod extends out of the interior of the mounting plate and is fixedly connected to an impeller, an air inlet is opened on the front side of the fixed frame, and an exhaust port is opened on the left side of the rotating drum; a screw is rotatably mounted on the front side of the fixed frame by a bearing, a movable frame is threadedly mounted on the outer surface of the screw, an extrusion block is fixedly connected to the rear side of the movable frame outside the screw, the rear side of the extrusion block extends to the interior of the fixed frame, a hand wheel is fixedly mounted on the front side of the screw, and a limiting component for limiting the screw is provided on the front side of the fixed frame; reinforcement components for reinforcing the bolt position are provided on both the left and right sides of the mounting plate.

[0007] Through the mutual cooperation between the movable frame and the screw, by rotating the screw, the movable frame can be driven to move toward the rear side, so that the extrusion block is close to the surface of the drum and the drum is squeezed and limited, which reduces the possibility of the drum rotating to a certain extent, thereby reducing the possibility of the blower vibrating during operation and ensuring that the blower can work normally. The installation of the handwheel can expand the contact area between the operator's hand and the screw to facilitate the rotation of the screw; and by rotating the screw in the opposite direction, the movable frame can be driven to move toward the front side, thereby separating the extrusion block from the surface of the drum, so that the drum can be rotated, thereby adjusting the direction of the exhaust port.

[0008] A further improvement of the technical solution of the present application is that: the reinforcing component includes a connecting plate, a spring is fixedly installed on the inner side of the connecting plate, a slide is fixedly connected to the inner side of the spring, a sliding rod is fixedly installed on the outer side of the slide inside the spring, the outer side of the slide is fixedly connected to the connecting plate, a baffle is fixedly installed on the inner side of the connecting plate on the rear side of the mounting plate, the front side of the baffle is in contact with the surface of the bolt, a first pull ring is fixedly installed on the outer side of the connecting plate, and a sealing frame is attached to the inside of the rotating cylinder outside the connecting plate, and the sealing frame is tightly in contact with the outer wall of the connecting plate.

[0009] The above-mentioned technical solution is adopted. In this solution, through the mutual cooperation between the reinforcement components, the elastic force of the spring itself can form an inward thrust on the slide plate, so that the baffle can be moved and fixed to the rear side of the bolt, so that the bolt can be limited and reinforced, thereby reducing the possibility of the bolt loosening due to vibration of the blower during operation, thereby improving the stability of the motor installation, thereby extending the overall service life of the blower, and by installing the first pull ring, the contact area between the operator's hand and the connecting plate can be expanded to facilitate the pulling operation of the connecting plate, wherein by pulling the first pull ring outward, the connecting plate moves synchronously, and the baffle can be moved outward and separated from the surface of the bolt, thereby facilitating the disassembly of the bolt and maintenance operations on the motor.

[0010] A further improvement of the technical solution of the present application is that: an inner surface of the baffle is provided with an inclined surface inclined toward the outer side of the front side.

[0011] The above technical solution is adopted. In this solution, by opening an inclined surface inclined toward the outer side of the front side on the inner surface of the baffle, the baffle can be easily moved inward and connected to the rear surface of the bolt, thereby preventing it from getting stuck.

[0012] A further improvement of the technical solution of the present application is that balls are rollingly mounted on the top and bottom and front and rear sides of the skateboard, and the balls are rollingly connected to the inner wall of the mounting plate.

[0013] The above-mentioned technical solution is adopted. In this solution, by arranging a number of ball bearings on the skateboard, the skateboard can be separated from the inner wall of the mounting plate. During the movement of the skateboard, the ball bearings can roll along the surface of the mounting plate, thereby reducing the wear between the skateboard and the mounting plate and extending their service life.

[0014] A further improvement of the technical solution of the present application is that: the limiting component includes a mounting frame, which is fixedly connected to the front side of the fixing frame, and a connecting rod is slidably installed on the top of the mounting frame. The bottom of the connecting rod passes through the interior of the mounting frame and is fixedly installed with a movable plate, and the movable plate is located at the top of the screw and the front side of the movable frame. A pair of side clamps are fixedly installed on the bottom of the movable plate, and the side clamps and the two sides of the screw are squeezed against each other, and the material of the side clamps is rubber material.

[0015] The above-mentioned technical solution is adopted. In this solution, through the mutual cooperation between the limiting components, the movable plate can be installed and moved by installing the mounting frame and the connecting rod, so that the movable plate can slide up and down and be limited and guided. By pushing the movable plate downward, the side clamps are set to a rubber material that can deform and rebound, and the two side clamps can be clamped to both sides of the screw rod, so that the screw rod can be limited to a certain extent, reducing the possibility of the screw rod rotating.

[0016] A further improvement of the technical solution of the present application is that a pressing block is fixedly installed at the bottom of the movable plate inside the side clamp, the bottom of the pressing block and the surface of the screw are pressed against each other, and the pressing block is made of rubber material.

[0017] The above-mentioned technical solution is adopted. In this solution, a top pressure block is installed and made of a rubber material that can deform and rebound. After the two side clamps are clamped to both sides of the screw, the lower surface of the top pressure block can contact and squeeze the surface of the screw, thereby further limiting the screw, reducing the possibility of the screw rotating, and improving the limiting effect of the extrusion block on the rotating drum.

[0018] A further improvement of the technical solution of the present application is that a second pull ring is fixedly connected to the top of the connecting rod.

[0019] The above-mentioned technical solution is adopted. In this solution, the contact area between the operator's hand and the connecting rod can be expanded by installing a second pull ring. By pulling the second pull ring toward the top, the connecting rod moves toward the top, and the side clamp and the top pressure block can be moved upward and separated from the surface of the screw, thereby facilitating the rotation operation of the screw.

[0020] A further improvement of the technical solution of the present application is that a connecting frame is fixedly installed inside the drum, and the rear side of the connecting frame is rotatably connected to the impeller.

[0021] The above-mentioned technical solution is adopted. In this solution, by installing a connecting frame and connecting the connecting frame to the impeller, the impeller can be installed and supported from the front side, reducing the possibility of deformation and bending of the rotating rod due to the excessive weight of the impeller, and reducing the possibility of vibration of the high-efficiency blower during operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The present application provides a high-efficiency blower, which is provided with a movable frame and a screw. By rotating the screw, the movable frame can be driven to move toward the rear side, and at the same time, the extrusion block is driven to squeeze and limit the rotating drum, which reduces the possibility of the rotating drum rotating to a certain extent, thereby reducing the possibility of the blower vibrating during operation, ensuring that the blower can work normally; by rotating the screw in the opposite direction and driving the movable frame to move toward the front side at the same time, the extrusion block can be separated from the surface of the rotating drum, so that the rotating drum can be rotated, thereby adjusting the direction of the exhaust port.
