Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to a blower for sewage treatment. Background Art

[0002] During the sewage treatment process, it is usually necessary to fully mix the reaction reagents with the sewage to help the sewage react better and achieve treatment. During the reaction process, a blower is usually used to help fully mix the reagents and sewage.

[0003] When the existing sewage treatment blower runs for a long time, the internal fan blades rotate to a large extent when the air is introduced, causing the internal parts of the blower to loosen, resulting in the blower shaking and reducing the stability of the equipment. At the same time, during the sewage treatment process, pipe stains can easily flow back through the airflow to the inner wall of the equipment and cause blockage, resulting in the equipment being unable to operate normally and reducing the blowing efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a blower for sewage treatment, which has the advantages of strong stability and good protection, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a blower for sewage treatment, comprising a body, a base fixedly mounted on the outer wall of the body, an air inlet fixedly mounted on the outer wall of the body, a round rod fixedly mounted on the inner wall of the base, a spring movably sleeved on the outer wall of the round rod, a slider slidably connected to the outer wall of the round rod, a square rod fixedly mounted on the outer wall of the slider, a circular plate fixedly mounted on the outer wall of the square rod, a motor fixedly mounted on the inner wall of the body, a fan blade rod fixedly mounted on the power output shaft of the motor, a block fixedly mounted on the outer wall of the body, a magnet provided on the inner wall of the block, and a straight rod provided on the bottom of the block.

[0006] As a preferred technical solution of the present invention: the number of the round rods is two, and the two round rods are symmetrically arranged with the square rod as the center.

[0007] As a preferred technical solution of the present invention: an air outlet is provided on the inner wall of the machine body, and the inner wall of the air outlet is matched with the outer wall of the circular plate.

[0008] As a preferred technical solution of the present invention: one end of the spring is fixed to the outer wall of the slider, and the other end of the spring is fixed to the outer wall of the body.

[0009] As a preferred technical solution of the present invention: the number of the magnets and blocks is two, and the magnets are respectively clamped on the inner walls of the two blocks, and the N poles of the two magnets are arranged correspondingly.

[0010] As an optimal technical solution of the present invention: the number of the straight rods is four, and the four straight rods are evenly distributed at the four corners of the block, the two blocks are respectively located at the two ends of the straight rod, and the block close to the bottom of the straight rod forms a sliding sleeve with the outer wall of the straight rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The blower for sewage treatment uses magnets to connect to the inner wall of the block when the fan rod is driven by the motor. The corresponding surfaces of the two magnets are of the same polarity. The repulsion between the two magnets is used to make the two magnets produce shock absorption, thereby avoiding excessive vibration during the rotation of the equipment and insufficient stability of the connection between the fan rod and the motor, which leads to loosening of the internal parts of the blower and shortening of its service life.

[0013] 2. The blower for sewage treatment uses airflow to push the circular plate to move. The circular plate drives the slider to compress the spring through the square rod, so that the stronger the airflow of the equipment, the wider the circular plate opens to the air outlet. When the equipment stops running, the elastic force of the spring pushes the circular plate to seal with the air outlet on the inner wall of the machine body to prevent dust and unknown organisms from entering the inner wall of the machine body and clogging it, resulting in reduced blower performance.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 - Figure 5 A blower for sewage treatment includes a body 1, a base 2 is fixedly mounted on the outer wall of the body 1, an air inlet 3 is fixedly mounted on the outer wall of the body 1, a round rod 4 is fixedly mounted on the inner wall of the base 2, a spring 5 is movably sleeved on the outer wall of the round rod 4, a slider 7 is slidably connected to the outer wall of the round rod 4, a square rod 6 is fixedly mounted on the outer wall of the slider 7, a circular plate 8 is fixedly mounted on the outer wall of the square rod 6, a motor 10 is fixedly mounted on the inner wall of the body 1, a fan blade rod 9 is fixedly mounted on the power output shaft of the motor 10, a block 12 is fixedly mounted on the outer wall of the body 1, a magnet 11 is provided on the inner wall of the block 12, and a straight rod 13 is provided at the bottom of the block 12.

[0022] In the above structure, by installing the air inlet 3 and using the motor 10 to rotate, the fan blade rod 9 rotates, and the external air enters the base 2 through the air inlet 3, and the air in the body 1 is discharged through the moving gap generated by the circular plate 8.

[0023] In a preferred embodiment, the number of the round rods 4 is two, and the two round rods 4 are symmetrically arranged with the square rod 6 as the center.

[0024] In the above structure, the two round rods 4 are symmetrically arranged with the square rod 6 as the center. The two round rods 4 are used to limit the circular plate 8 to avoid position deviation.

[0025] In a preferred embodiment, an air outlet is provided on the inner wall of the machine body 1 , and the inner wall of the air outlet is matched with the outer wall of the circular plate 8 .

[0026] In the above structure, the inner wall of the air outlet is adapted to the outer wall of the circular plate 8, and the motor 10 is used to drive the fan blade rod 9 to rotate to generate airflow to push the circular plate 8, so that the air outlet can discharge air. When the equipment stops running, the airflow disappears, and the circular plate 8 shields the air outlet to prevent organisms from entering the inner wall of the equipment and causing damage to the equipment.

[0027] In a preferred embodiment, one end of the spring 5 is fixed to the outer wall of the slider 7 , and the other end of the spring 5 is fixed to the outer wall of the body 1 .

[0028] In the above structure, the circular plate 8 is pushed by the airflow to move, and the circular plate 8 drives the slider 7 to compress the spring 5 through the square rod 6, so that the stronger the airflow of the equipment, the larger the circular plate 8 opens to the air outlet. When the equipment stops running, the circular plate 8 is pushed by the elastic force of the spring 5 to seal with the air outlet on the inner wall of the body 1, preventing dust and unknown organisms from entering the inner wall of the body 1 and clogging it, resulting in reduced performance of the blower.

[0029] In a preferred embodiment, the number of the magnets 11 and the number of the blocks 12 are both two, and the magnets 11 are respectively connected to the inner walls of the two blocks 12, and the N poles of the two magnets 11 are arranged correspondingly.

[0030] In the above structure, when the fan rod 9 is driven to rotate by the motor 10, the magnets 11 are respectively clamped on the inner wall of the block 12. The corresponding surfaces of the two magnets 11 are of the same polarity. The repulsion between the two magnets 11 is utilized to make the two magnets 11 produce shock absorption, thereby avoiding excessive vibration during the rotation of the equipment, and the connection between the fan rod 9 and the motor 10 is not firm enough, which causes the internal parts of the blower to loosen and reduces the service life.

[0031] In a preferred embodiment, there are four straight rods 13 , and the four straight rods 13 are evenly distributed at the four corners of the block 12 . Two blocks 12 are respectively located at both ends of the straight rod 13 , and the block 12 close to the bottom of the straight rod 13 forms a sliding sleeve with the outer wall of the straight rod 13 .

[0032] In the above structure, the two blocks 12 are respectively located at the two ends of the four magnets 11, so that the magnets 11 can limit the blocks 12, thereby preventing the blocks 12 from shifting in position during the shock absorption process, thereby increasing the stability of the device.

[0033] Working principle: By placing the device on the ground and using the motor 10 to rotate, the fan rod 9 rotates, and the external air enters the body 1 through the air inlet 3, and the air in the body 1 is discharged through the gap created by the movement of the circular plate 8. When the motor 10 drives the fan rod 9 to rotate, the magnets 11 are respectively connected to the inner wall of the block 12. The corresponding surfaces of the two magnets 11 are of the same sex. The same sex repulsion between the two magnets 11 is used to make the two magnets 11 produce shock absorption to avoid excessive vibration during the rotation of the device. The connection between the fan rod 9 and the motor 10 is not stable enough, and the circular plate 8 is pushed by the airflow to move. The circular plate 8 drives the slider 7 to compress the spring 5 through the square rod 6, so that the stronger the airflow of the device, the larger the circular plate 8 opens to the air outlet. When the device stops running, the circular plate 8 is pushed by the elastic force of the spring 5 to seal with the air outlet on the inner wall of the body 1 to prevent dust and unknown organisms from entering the inner wall of the body 1 and clogging it, resulting in reduced performance of the blower.
