Description

Technical Field

[0001] The utility model relates to the technical field of blower sealing, in particular to a blower with strong connection sealing performance. Background Art

[0002] The working principle of the counterflow cooling tower is to use the natural convection of air to draw air into the cooling tower and exchange heat with water. The heat exchange process is as follows: water flows down from the surface of the filler, exchanges heat with the air, transfers heat to the air, and lowers its own temperature; while the air absorbs the heat of the water and its temperature rises;

[0003] This design makes the cooling process more efficient and can operate stably under different water temperatures, pressures and other conditions. Because the resistance of the mist elimination module is higher than that of conventional fillers, and the arrangement and combination of the mist elimination modules are more complex, conventional induced draft fans cannot provide a sufficiently large total pressure.

[0004] Under the influence of the environment, the temperature is low in winter. Affected by thermal expansion and contraction, a gap will appear between the blower and the fan channel under the influence of low temperature, causing air leakage during the operation of the blower, thus affecting the working efficiency and quality of the cooling tower. Therefore, it is necessary to design a blower with a strong connection sealing effect with sealing and thermal insulation effect. Utility Model Content

[0005] The utility model aims to provide a blower with strong connection sealing performance in view of the existing technical defects, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a blower with strong connection sealing, including a blower sealed and installed in a fan channel of a cooling tower, the blower including a blower casing, and a hydrophobic rock wool board is filled between the outer wall of the blower casing and the fan channel.

[0007] The utility model further illustrates that a front end plate and a rear end plate which are sealed to the fan channel are fixedly connected in sequence from left to right along the axial direction of the blower housing.

[0008] The utility model further illustrates that shock-absorbing rubber pads are arranged between the front end plate and the rear end plate and the inner wall of the fan channel.

[0009] The utility model further illustrates that a cavity one is opened in the blower shell, a motor frame is fixedly connected in the cavity one, a motor is fixedly connected to the motor frame, and a blower blade is fixedly connected to the output end of the motor.

[0010] The utility model further describes that the motor frame includes a sleeve and multiple groups of connecting plates, the multiple groups of connecting plates are evenly arranged in a circle with the axis of the sleeve as the center, and the motor is fixedly connected in the sleeve.

[0011] The utility model further describes that the blower casing is cylindrical, the cavity one is cylindrical, and the axis line of the sleeve coincides with the axis line of the cavity one, thereby preventing the motor from generating eccentric force on the blower casing during operation, thereby reducing the sealing effect between the blower and the fan channel.

[0012] The utility model further illustrates that a shutter is installed on the side of the front end plate away from the rear end plate.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model uses a hydrophobic rock wool board to perform thermal insulation and waterproof filling of the gap between the blower and the fan channel;

[0014] By adding shock-absorbing pads and sealing connections between the front and rear plates and the fan channel, the sealing and shock-absorbing effects of the blower under the influence of temperature are improved;

[0015] By setting up shutters, the air intake can be controlled to reduce air leakage;

[0016] By placing the fan channel outside the tower and placing the blower at the end of the fan channel, long-term erosion by hot and humid gas can be avoided and the service life of the blower can be extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 , the utility model provides a technical solution: a blower with strong connection sealing, comprising a cooling tower 1, a fan channel 2 is arranged on the side of the cooling tower 1, the fan channel 2 is connected to the cooling tower 1, and a blower 3 is arranged in the fan channel 2;

[0023] Reference Figure 2 The blower 3 includes a blower housing 301, to which a front end plate 302 and a rear end plate 303 are fixedly connected in sequence from left to right along the axial direction of the blower housing 301. The outer walls of the front end plate 302 and the rear end plate 303 are fixedly connected to the inner wall of the blower channel 2 by bolts. A shutter 9 is installed on the side of the front end plate 302 away from the rear end plate 303. The shutter 9 is used to control the amount of air intake, thereby adjusting the defogging effect.

[0024] Shock-absorbing rubber pads are arranged between the front end plate 302 and the rear end plate 303 and the inner wall of the fan channel 2, which are used to reduce the impact of the vibration of the blower 3 on the fan channel 2 during the operation of the blower 3, improve the stability of the connection between the blower 3 and the fan channel 2, and have a certain sealing effect.

[0025] The blower housing 301 is cylindrical, and a cavity 4 is provided in the blower housing 301. The cavity 4 is cylindrical, and a motor frame 5 is fixedly connected to the cavity 4.

[0026] The motor frame 5 includes a sleeve 501, in which the motor 6 is fixedly connected. The axis of the sleeve 501 coincides with the axis of the cavity 4, so as to prevent the motor 6 from generating an eccentric force on the blower housing 301 during operation, thereby preventing cracks from being generated at the connection between the blower 3 and the fan channel 2 under the action of the eccentric force, thereby affecting the sealing effect.

[0027] The output end of the motor 6 is fixedly connected to the fan blade 7 on the side facing the front end plate 302;

[0028] The outer wall of the sleeve 501 is fixedly connected with multiple groups of connecting plates 502. Specifically, there are four groups of connecting plates 502. The four groups of connecting plates 502 are evenly arranged at 90° with the axis of the sleeve 501 as the center of the circle. The side of the connecting plate 502 away from the sleeve 501 is fixedly connected to the inner wall of the cavity 4. The motor frame 5 and the blower casing 301 are firmly connected through the four groups of connecting plates 502, thereby reducing the vibration effect of the motor 6 on the blower casing 301 during operation, further reducing the vibration effect of the blower 3 on the fan channel 2, and indirectly improving the sealing connection effect between the blower 3 and the fan channel 2.

[0029] A hydrophobic rock wool board 8 is filled between the outer wall of the blower housing 301 and the fan channel 2 to serve as a heat-insulating and waterproof board. At the same time, the filling provides a certain sealing effect between the outer wall of the blower housing 301 and the fan channel 2.

[0030] In this embodiment, during on-site installation, the rear end plate 303 is first removed from the blower 3, the blower 3 is placed in the fan channel 2 and stabilized, and a circle of shock-absorbing rubber pads is placed between the front end plate 302 and the inner wall of the fan channel 2, and sealed with sealant;

[0031] Then, the outer wall of the blower housing 301 and the fan channel 2 are filled with a hydrophobic rock wool board 8. After the filling is completed, the rear end plate 303 is fixed on the blower 3, and a circle of shock-absorbing rubber pads are placed between the rear end plate 303 and the fan channel 2, and sealed with a sealant;

[0032] Then, the front end plate 302 and the rear end plate 303 are fixedly connected to the fan channel 2 by means of bolts, and finally the shutter 9 is fixed to the front end plate 302 to complete the installation.
