Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilation devices, and particularly relates to a ventilation device for a glass furnace fan room. Background Technique
[0002] During the glass manufacturing process, a large amount of air flow is required to control the furnace temperature and ventilation to ensure the stability of glass quality. The main function of the fan room is to provide sufficient ventilation and air flow to support the normal operation of the glass furnace. In the fan room, multiple fans are usually installed to adjust the air flow rate and pressure. These fans can be centrifugal fans, axial fans, etc., and are selected according to actual needs. The design and maintenance of the fan room are also very important, and it is necessary to ensure the normal operation of the fans, regular cleaning and inspection to prevent failures and improve energy efficiency.
[0003] Since the temperature is high when the glass furnace is working, the temperature in the fan room located near the glass furnace will accumulate and rise. However, too high a temperature in the fan room will affect the working performance of the fans. Therefore, it is necessary to cool the inside of the fan room. The existing cooling measures are to install a ventilation device in the fan room for the internal and external air exchange of the fan room, discharge the high-temperature gas to the outside of the fan room, and divert the low-temperature external air into the fan room to achieve cooling to ensure the normal operation of the fans.
[0004] However, the inlet of the traditional ventilation device is fixedly arranged, and the ventilation coverage is limited, resulting in insufficient ventilation in some areas of the fan room, which makes the temperature distribution in the fan room uneven and the heat dissipation effect poor. Content of the Utility Model
[0005] The purpose of the utility model is to provide a ventilation device for a glass furnace fan room with good heat dissipation effect, which effectively solves the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions.
[0007] A ventilation device for a glass furnace fan room includes a ventilation cylinder and a flow collecting tank. The ventilation cylinder is arranged on the top of the fan room, the top of the ventilation cylinder extends to the outside of the fan room, and the bottom extends to the inside of the fan room. The flow collecting tank is fixed at the bottom of the ventilation cylinder, the bottom end of the flow collecting tank is sealed, and the top end is communicated with the bottom of the ventilation cylinder. An exhaust mechanism is arranged in the ventilation cylinder. A plurality of square diversion pipes are arranged at intervals on the outer wall of the flow collecting tank. Each square diversion pipe is communicated with the flow collecting tank, and each square diversion pipe extends horizontally. The lower surface of each square diversion pipe is provided with inlets at intervals along the length direction of the square diversion pipe. Each inlet extends vertically and is correspondingly communicated with the square diversion pipe.
[0008] It can be seen that since the square diversion pipes are arranged at intervals on the outer wall of the header tank, and a number of vertically extending inlet ports are evenly distributed on each square diversion pipe, radial inlet points are provided at the top of the fan room, ensuring a large coverage area of the exhaust range, making the ventilation area no longer limited, reducing the air retention in local areas of the fan room, ensuring more uniform air flow in the fan room, and achieving better ventilation and heat dissipation effects. In addition, the square diversion pipes are arranged at the top of the fan room, and the inlet ports are arranged below the square diversion pipes and extend vertically. Therefore, when ventilating, the air in the fan room flows from bottom to top. Combining with the principle of hot air buoyancy, the hot air flow with too high temperature in the fan room will also flow upward, thus forming a convection cycle from bottom to top in the fan room, enhancing the ventilation effect and accelerating the discharge of the high-temperature air flow, further improving the heat dissipation effect.
[0009] Furthermore, there are six square diversion pipes, and the six square diversion pipes are arranged in an annular array around the header tank. One end of each square diversion pipe far from the header tank is sealed, and the ends close to the header tank are respectively fixedly connected to the header tank.
[0010] Furthermore, the exhaust mechanism includes a bracket, a mounting seat, a driving motor and a fan blade. The mounting seat is installed in the ventilation duct through the bracket. The driving motor is fixed at the lower end of the mounting seat, and the fan blade is fixedly installed on the output shaft of the driving motor.
[0011] Furthermore, a buffer sleeve is fixedly sleeved outside the ventilation duct, and the buffer sleeve is made of rubber material.
[0012] Furthermore, a first filter screen is installed near the top end inside the ventilation duct, and a second filter screen is installed in each inlet port.
[0013] Furthermore, a lifting rod is fixed on one side of the top of each square diversion pipe far from the header tank. Each lifting rod extends vertically, and the top end of each lifting rod is fixedly connected to a fixing seat. Each fixing seat is respectively fastened to the ceiling of the fan room through expansion screws.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows.
[0015] 1. In the present utility model, since the square diversion pipes are arranged at intervals on the outer wall of the header tank, and a number of vertically extending inlet ports are evenly distributed on each square diversion pipe, radial inlet points are provided at the top of the fan room, ensuring a large coverage area of the exhaust range, making the ventilation area no longer limited, reducing the air retention in local areas of the fan room, ensuring more uniform air flow in the fan room, and achieving better ventilation and heat dissipation effects.
[0016] 2. The square diversion pipe in the present utility model is arranged at the top of the fan room, and the inlet is arranged below the square diversion pipe and extends vertically. Thus, when ventilating, the air in the fan room flows from bottom to top. Combining with the principle of hot air buoyancy, the airflow with too high temperature in the fan room will also flow upward. Therefore, a convection cycle from bottom to top is formed in the fan room, enhancing the ventilation effect and accelerating the discharge of the high-temperature airflow, further improving the heat dissipation effect.

[0024] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0025] Please refer to Figures 1 - 4 , a ventilation device for a glass furnace blower room provided by the present utility model includes a ventilation cylinder 1 and a flow collector 2. The ventilation cylinder 1 is arranged on the top of the blower room. The top of the ventilation cylinder 1 extends to the outside of the blower room, and the bottom extends to the inside of the blower room. The flow collector 2 is fixed to the bottom of the ventilation cylinder 1. The bottom end of the flow collector 2 is sealed, and the top end is connected to the bottom of the ventilation cylinder 1 in communication. An exhaust mechanism 3 is provided in the ventilation cylinder 1. A plurality of square diversion pipes 4 are arranged at intervals on the outer wall of the flow collector 2. Each square diversion pipe 4 communicates with the flow collector 2, and each square diversion pipe 4 extends horizontally. On the lower surface of each square diversion pipe 4, intake ports 41 are arranged at intervals along the length direction of the square diversion pipe 4. Each intake port 41 extends vertically and communicates with the square diversion pipe 4 correspondingly.
[0026] The ventilation cylinder 1 in this ventilation device is vertically installed through the top of the blower room. By the operation of the exhaust mechanism 3, a vertically upward air flow is generated in the ventilation cylinder 1. Then, the air in the blower room is vertically sucked upward into the square diversion pipe 4 through the intake ports 41, and then horizontally diverted to the flow collector 2 through the square diversion pipe 4, and finally converges into the ventilation cylinder 1 and is discharged to the outside of the blower room from the top end of the ventilation cylinder 1. An intake pipe (not shown in the figure) is also provided in the blower room. The intake pipe extends to a position far from the glass furnace. When the air in the blower room is discharged, in order to ensure air pressure balance, the cold air outside is supplemented into the blower room through the intake pipe, realizing the air exchange outside the blower room, and thus achieving the cooling effect.
[0027] In addition, since the square flow guide pipes 4 are arranged at intervals on the outer wall of the header tank 2, and a number of vertically extending inlet ports 41 are evenly distributed on each square flow guide pipe 4, a radially distributed inlet point is provided at the top of the fan room, ensuring a large coverage area of the exhaust range, so that the ventilation area is no longer limited, reducing the air retention in local areas of the fan room, ensuring more uniform air flow in the fan room, and achieving better ventilation and heat dissipation effects.
[0028] Secondly, the square flow guide pipes 4 are arranged at the top of the fan room, and the inlet ports 41 are arranged below the square flow guide pipes 4 and extend vertically. Therefore, when ventilating, the air in the fan room flows from bottom to top. Combining with the principle of hot air buoyancy, the hot air flow with too high temperature in the fan room will also flow upward, thus forming a convection cycle from bottom to top in the fan room, enhancing the ventilation effect and accelerating the discharge of the high-temperature air flow, further improving the heat dissipation effect.
[0029] Specifically, there are six square flow guide pipes 4, and the six square flow guide pipes 4 are arranged in an annular array around the header tank 2. One end of each square flow guide pipe 4 away from the header tank 2 is sealed, and the end close to the header tank 2 is fixedly connected to the header tank 2 respectively. The six square flow guide pipes 4 are arranged in an array around the header tank 2, so that the inlet ports 41 are distributed evenly enough above the interior of the fan room, thereby improving the multi-point exhaust and inlet effect.
[0030] Specifically, the exhaust mechanism 3 includes a bracket 31, a mounting seat 32, a driving motor 33 and a fan blade 34. The mounting seat 32 is installed in the ventilation cylinder 1 through the bracket 31. The driving motor 33 is fixed at the lower end of the mounting seat 32, and the fan blade 34 is fixedly installed on the output shaft of the driving motor 33. By operating the driving motor 33, its output shaft drives the fan blade 34 to rotate, and the air inside the ventilation cylinder 1 can be blown upward to the outside, thereby realizing a vertically upward air flow in the ventilation cylinder 1 and achieving the exhaust effect.
[0031] Specifically, a buffer sleeve 12 is fixedly sleeved outside the ventilation cylinder 1. The buffer sleeve 12 is made of rubber material. The ventilation cylinder 1 is specifically installed in the installation hole opened at the top of the fan room. By sleeving the buffer sleeve 12 outside the ventilation cylinder 1, the buffer sleeve 12 abuts against the installation hole. The buffer sleeve 12 made of rubber material has a buffer and shock absorption effect. On the one hand, it can filter the vibration generated by the operation of the exhaust mechanism 3, and on the other hand, it can prevent the outer wall of the ventilation cylinder 1 from directly contacting the inner wall of the installation hole and generating excessive abnormal noises, killing two birds with one stone.
[0032] Specifically, a first filter screen 11 is installed near the top inside the ventilation duct 1. On the one hand, when the entire ventilation device is not working, the first filter screen 11 can prevent particulate matters such as dust from entering the ventilation duct 1, the flow collecting tank 2, and the square diversion pipe 4, thus avoiding pollution. On the other hand, it has an interception effect to prevent other external objects from falling into the ventilation duct 1 and colliding with the fan blade 34 during operation, which may cause damage to the fan blade 34. A second filter screen 42 is installed in each inlet 41. The second filter screen 42 can filter out the dust particulate matters in the air entering the square diversion pipe 4, avoiding pollution caused by entering the ventilation duct 1, the flow collecting tank 2, and the square diversion pipe 4.
[0033] Specifically, a hoisting rod 401 is fixed on one side of the top of each square diversion pipe 4 away from the flow collecting tank 2. Each hoisting rod 401 extends vertically, and the top of each hoisting rod 401 is fixedly connected with a fixing seat 402. Each fixing seat 402 is fastened to the ceiling of the fan room by expansion screws. The hoisting rod 401 and the fixing seat 402 can provide an upward traction and support effect for the square diversion pipe 4, ensuring that the horizontally extending square diversion pipe 4 is more stable, and thus improving the overall stability of the structure.
[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
