Description

An energy-saving axial flow fan for textile use

Technical Field

The invention belongs to the technical field of ventilators, and in particular relates to an energy-saving axial flow ventilator for textile use.

Background technique

Energy-saving axial flow fans, also known as local fans, are a type of fan commonly used by enterprises for local ventilation. Its working principle is based on axial flow design, that is, the gas flows parallel to the fan axis. Energy-saving axial flow fans are characterized by large flow, small volume, and low pressure head. The working method of its blades is similar to that of an airplane wing, but unlike ordinary fans, its motor and fan blades are in a cylinder, and the appearance is a cylinder. This design makes the fan easy to install, the ventilation effect is obvious, and it is safe. Fans are often used in common industrial production processes to ventilate the environment.

In textile workshops, ventilators are often used to ventilate the environment. In order to improve the ventilation effect, conventional ventilators are generally installed near the ceiling of the workshop. Although this installation method is safer and can achieve better ventilation effect, it is extremely inconvenient to maintain, especially in textile workshops. Since there are a lot of wool in the textile workshop, the ventilator will be contaminated with a lot of wool after being used for a period of time, resulting in poor ventilation effect. The existing technology requires maintenance personnel to climb to a high place and use brushes to clean manually. The overall risk factor is high and cleaning is inconvenient.

When using axial flow fans to ventilate textile workshops, since the hair debris generated in the textile workshop is small in size, this hair debris can easily pass through the dust net and enter the inside of the fan shell and adhere to the inner side of the shell. As a result, during the operation of the fan, some of the hair debris is lifted up due to the airflow changes brought by the fan blades, which in turn causes certain air pollution. The inside of the shell needs to be disassembled before the fan can be cleaned, and rapid and automatic cleaning cannot be achieved, and improvement is urgently needed.

Summary of the invention

The object of the present invention is to provide an energy-saving axial flow fan for textile use to solve the problems raised in the above-mentioned background technology.

In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an energy-saving axial flow fan for textile use, comprising a casing, a dustproof net is installed on the front side of the casing by bolts, an extension tube is fixedly installed in the middle of the front side of the dustproof net, a mounting shaft is provided at a position near the front end inside the casing, fan blades are fixedly installed at equal angles on the outer side surface of the mounting shaft, a power sleeve is installed at a position near the outer side surface of the rear end of the mounting shaft, a mounting frame is fixedly installed at a position near the rear end of the casing, a motor is installed at the front end of the mounting frame, a bearing is installed at the front end of the motor output shaft, the front end of the bearing is connected to the rear end of the power sleeve, an auxiliary cleaning component is fixedly sleeved on the outer side surface of the power sleeve, a cleaning plate is provided between the rear end of the dustproof net and the front end of the fan blade, the rear end of the cleaning plate is fixedly connected to a limiting plate, and the rear end of the limiting plate is fixedly connected to a movable shaft.

In actual use, the casing can be fixed on the ground through the base, or the base at the bottom of the casing can be removed through the installation groove and the device can be installed at a high place for ventilation of the workshop. During ventilation, the bearing and the power sleeve at the front end can be driven to rotate by starting the motor. At this time, the installation shaft rotates accordingly, and the fan blades on the outer side are driven to rotate circumferentially simultaneously, so that airflow can be generated to realize ventilation in the workshop.

As a further technical solution of the present invention, the front end of the extension tube is fixedly connected to a rotating shaft, and the rear end of the rotating shaft is movably connected to a first electric telescopic rod. The output end of the first electric telescopic rod sequentially passes through the rear ends of the extension tube and the dustproof net and is connected to the middle part of the front end of the cleaning plate.

As a further technical solution of the present invention, a through slot is provided in the middle of the installation shaft and is movably sleeved with the movable shaft, and the movable shaft is displaced forward and backward relative to the through slot.

As a further technical solution of the present invention, a limiting groove is provided in the middle of the front end of the installation shaft, a clamping groove is provided in the middle of the rear end of the installation shaft, and a clamping block is fixedly connected to the rear end of the movable shaft.

As a further technical solution of the present invention, when the front end of the cleaning plate contacts the rear end of the dustproof net, the clamping block and the clamping groove are movably clamped, and when the rear end of the cleaning plate contacts the front end of the fan blade, the limiting plate is located inside the limiting groove and movably sleeved with the limiting groove.

When it is necessary to clean the back of the dust net, the first electric telescopic rod can be controlled to shorten to the minimum length, and the cleaning plate can be driven to move forward and backward until the front end of the cleaning plate contacts the rear end of the dust net. At this time, the clamping block at the rear end of the movable shaft is just clamped with the clamping groove to complete the fixation. At this time, the power transmission is completed, and the cleaning plate can rotate with the installation shaft. At this time, the cleaning plate can rotate relative to the dust net to assist in cleaning the rear end of the dust net to avoid dust accumulation.

When the surface of the fan blade needs to be cleaned, the first electric telescopic rod can be turned on and controlled to extend, and the cleaning plate can be driven to move backward until the limit plate enters the limit groove. At this time, the back of the cleaning plate can contact the front of the fan blade, and the cleaning plate will not rotate with the installation shaft. At this time, the fan blade continues to rotate and contacts the cleaning plate in a stationary state, completing the auxiliary cleaning process of the fan blade surface.

By utilizing a cleaning plate that can be moved forward and backward, and utilizing the forward displacement of the cleaning plate to make it contact with the rear end of the dust screen, power transmission can be achieved, that is, the dust screen in a stationary state can be cleaned by the rotating cleaning plate to complete the auxiliary cleaning process. At the same time, the cleaning plate can be moved backward to make it contact with the front end of the fan blade, and the self-rotating fan blade can be used to cooperate with the stationary cleaning plate to perform the cleaning process. The whole process is automatically completed and the dust screen and the fan blade can be cleaned separately, which can effectively avoid the problem that traditional cleaning methods are difficult to clean and reduce the number of maintenance times.

As a further technical solution of the present invention, a water inlet groove is opened in the middle of the top of the casing, and a timing valve located directly above the water inlet groove is fixedly installed on the outer side of the casing. The top of the timing valve is fixedly connected to a water storage pipe, and the top of the water storage pipe is fixedly connected to a water inlet.

As a further technical solution of the present invention, one end of the water inlet away from the water storage pipe is connected to an external water pipe, and the valve opening interval of the timing valve is controlled by an external control panel.

When it is necessary to clean the inside of the casing, the regular opening time of the timing valve can be set, that is, the water flow inside the water storage pipe is regularly introduced into the interior of the casing and auxiliary cleaning components are used for auxiliary cleaning. After completing the first water flow export, the timing valve is automatically closed, and the external water flow enters the water storage pipe through the water inlet and waits for the second export process.

As a further technical solution of the present invention, the auxiliary cleaning component includes a transfer sleeve, the inner side of the transfer sleeve is fixedly connected to the outer side of the power sleeve, and the auxiliary cleaning component also includes an arc-shaped cleaning block, which is arranged at an equal angle on the outer side of the transfer sleeve.

As a further technical solution of the present invention, magnets are adsorbed and fixed at equal angles on the outer side of the transfer sleeve, a second electric telescopic rod is installed at the end of the magnet away from the transfer sleeve, and the output end of the second electric telescopic rod is connected to the middle part of the arc-shaped cleaning block close to one end of the transfer sleeve.

When the inner wall of the casing needs to be cleaned, the second electric telescopic rod can be turned on to extend the second electric telescopic rod. At this time, the arc-shaped cleaning block can be controlled to move toward the outer side of the casing until the outer side of the arc-shaped cleaning block contacts the inner wall of the casing. At this time, the rotation of the power sleeve can drive the arc-shaped cleaning block to rotate circumferentially relative to the inner wall of the casing and cooperate with the derived water flow to complete the cleaning process of the inner wall of the casing, thereby completing the automatic cleaning of the inner wall of the casing.

By utilizing the rotating motion of the fan blades when they are working, the dust screen and the surface of the fan blades can be cleaned while the inner wall of the casing can be automatically cleaned. The entire cleaning process is still completed automatically, avoiding the problem of traditional devices requiring the device to be disassembled before the inside can be cleaned. It effectively avoids the dust phenomenon caused by hair and dust, improves the air cleanliness when the device is working, and thus improves the overall environment of the workshop.

The beneficial effects of the present invention are as follows:

1. The present invention utilizes a cleaning plate that can be displaced forward and backward. The forward displacement of the cleaning plate makes it contact with the rear end of the dust screen, and power transmission can be achieved. That is, the dust screen in a stationary state is cleaned by the rotating cleaning plate to complete the auxiliary cleaning process. At the same time, the cleaning plate can be displaced backward to make it contact with the front end of the fan blade, and the self-rotating fan blade can be used to cooperate with the stationary cleaning plate to perform the cleaning process. The whole process is automatically completed and the dust screen and the fan blade can be cleaned separately, which can effectively avoid the problem that the traditional cleaning method is difficult to clean and reduce the number of maintenance times.

2. The present invention utilizes the rotating action of the fan blades when they are working. While using the rotating action to clean the dust screen and the surface of the fan blades, it can also automatically clean the inner wall of the casing.

Working principle and usage process:

When in use, the housing 1 can be fixed on the ground through the base 3, or the base 3 at the bottom of the housing 1 can be removed through the installation groove to install the device at a high place for ventilation of the workshop. During ventilation, the bearing 16 and the power sleeve 15 at the front end can be driven to rotate by starting the motor 18, and the installation shaft 13 rotates accordingly, and synchronously drives the fan blades 14 on the outer side to rotate circumferentially, so that airflow can be generated to realize ventilation in the workshop;

When it is necessary to clean the back of the dust-proof net 2, the first electric telescopic rod 6 can be controlled to shorten to the minimum length, and the cleaning plate 7 can be driven to move forward and backward until the front end of the cleaning plate 7 contacts the rear end of the dust-proof net 2. At this time, the clamping block 11 at the rear end of the movable shaft 8 is just clamped with the clamping groove 12 to complete the fixation. At this time, the power transmission can be completed, and the cleaning plate 7 can rotate with the installation shaft 13. At this time, the cleaning plate 7 can rotate relative to the dust-proof net 2 to assist in cleaning the rear end of the dust-proof net 2 to avoid dust accumulation;

When it is necessary to clean the surface of the fan blade 14, the first electric telescopic rod 6 can be turned on and controlled to extend, and the cleaning plate 7 can be driven to move backward until the limiting plate 9 enters the limiting groove 10. At this time, the back of the cleaning plate 7 can contact the front of the fan blade 14, and the cleaning plate 7 will not rotate with the mounting shaft 13. At this time, the fan blade 14 continues to rotate and contacts the cleaning plate 7 in a stationary state, completing the auxiliary cleaning process of the surface of the fan blade 14;

When it is necessary to clean the interior of the housing 1, the regular opening time of the timing valve 21 can be set, that is, the water flow inside the water storage pipe 19 is regularly introduced into the interior of the housing 1 and the auxiliary cleaning component 23 is used for auxiliary cleaning. After the first water flow is discharged, the timing valve 21 is automatically closed, and the external water flows into the interior of the water storage pipe 19 through the water inlet 20 to wait for the second discharge process;

When the inner wall of the casing 1 needs to be cleaned, the second electric telescopic rod 233 can be turned on to extend the second electric telescopic rod 233. At this time, the arc cleaning block 232 can be controlled to move toward the outer side of the casing 1 until the outer side of the arc cleaning block 232 contacts the inner wall of the casing 1. At this time, the rotation of the power sleeve 15 can drive the arc cleaning block 232 to rotate circumferentially relative to the inner wall of the casing 1 to cooperate with the derived water flow, thereby completing the cleaning process of the inner wall of the casing 1 and completing the automatic cleaning of the inner wall of the casing 1.
