Description

Technical Field

[0001] The utility model relates to the technical field of ventilation systems, in particular to an energy-saving ventilation system for a factory building. Background Art

[0002] Ventilation is a building environment control technology that controls the spread and harm of air pollutants by means of ventilation dilution or ventilation exhaust, etc., to ensure the indoor and outdoor air environmental quality. The ventilation system is a set of devices that realizes the function of ventilation, including air inlets, air outlets, air supply ducts, fans, cooling and heating, filters, control systems, and other auxiliary equipment.

[0003] At present, the existing factory buildings discharge the purified air through the ventilation system to keep the air inside the factory building fresh. However, the outdoor air temperature is higher than the indoor temperature. In the long run, it is easy to make the air inside the factory building too dry. Too low indoor air humidity will easily lead to a decline in the immunity of the staff. In addition to discharging the purified air, the existing ventilation system also extracts and discharges the indoor air. However, the air inside the factory building is turbid. If the ventilation system runs for a long time, it is easy to cause the filter screen of the air extraction grille to be blocked. The installation position of the ventilation system is relatively high, which is not conducive to the staff to replace and install the filter screen. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to provide an energy-saving ventilation system for a factory building.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An energy-saving ventilation system for a factory building includes a first lower pipe, an annular pipe, and an exhaust grille. A fan is installed at the top of the first lower pipe. A net plate is provided at the bottom of the fan and is installed at the bottom end of the first lower pipe. The net plate is located at the bottom of the exhaust grille. The top of the exhaust grille is fixedly connected to the bottom of the first lower pipe. A number of retaining rings are installed between the exhaust grille and the net plate. The annular pipe is installed on the retaining rings. One end of the annular pipe penetrates through the net plate and the first lower pipe. A number of atomizing heads are installed at the bottom of the annular pipe, and the atomizing heads are located at the top of the intake grille.

[0007] As a further solution of the utility model, a discharge air duct is provided at the top of the first lower pipe. The first lower pipe is installed at the bottom of the discharge air duct, and the fan is located inside the discharge air duct.

[0008] As a further solution of the utility model, a ventilation device is provided on one side of the first lower pipe. The discharge air duct is installed on one side of the ventilation device, and an intake pipe is installed on the side of the ventilation device away from the discharge air duct.

[0009] As a further solution of the present utility model, a second lower pipe is installed on one side of the bottom of the intake pipe. A plurality of electric push rods are installed in the inner wall of the second lower pipe, and an intake grille is installed at the bottom of the second lower pipe.

[0010] As a further solution of the present utility model, the telescopic rod of the electric push rod is installed at the bottom of the intake grille. Sliding grooves are respectively formed on both sides of the inner wall of the second lower pipe, and a clamping pipe is installed at the top of the intake grille.

[0011] As a further solution of the present utility model, both sides of the outside of the clamping pipe are clamped and connected inside the sliding grooves. A filter element is installed inside the clamping pipe, and the bottom of the filter element is attached to the top of the intake grille.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. In order to maintain the humidity of the gas inside the factory building, when the air is discharged, the annular pipe is opened. The annular pipe transports the water flow to the atomizing head. The water flow is converted into a mist by the atomizing head and discharged into the first lower pipe. The fan extracts the air inside the exhaust pipe, so that the air inside the first lower pipe carries the water mist into the factory building to maintain the humidity of the air inside the factory building.

[0014] 2. The turbid air inside the factory building enters the intake pipe through the intake grille. The air passes through the intake grille and is filtered by the filter element. However, long-term filtration causes the filter element to become blocked, weakening the air fluidity. At this time, the staff starts the electric push rod. The electric push rod drives the intake grille to move downward so that the intake grille reaches a height that can be touched by the staff. The staff replaces the filter element inside the clamping pipe. Then, the electric push rod is started again, and the electric push rod drives the filter element and the intake grille to reset, which is convenient for the staff to replace the filter element inside the intake pipe.

A fan 2 is installed at the top of the first lower pipe 1. A mesh plate 3 is provided at the bottom of the fan 2. The mesh plate 3 is installed at the bottom end of the first lower pipe 1. The mesh plate 3 is located at the bottom of the exhaust grille 6. The top of the exhaust grille 6 is fixedly connected to the bottom of the first lower pipe 1. A plurality of retaining rings 5 are installed between the exhaust grille 6 and the mesh plate 3. The annular pipe 4 is installed on the retaining rings 5. One end of the annular pipe 4 penetrates through the mesh plate 3 and the first lower pipe 1. A plurality of atomizing heads 401 are installed at the bottom of the annular pipe 4. The atomizing heads 401 are located at the top of the intake grille 6.

[0024] During use, in order to maintain the humidity of the gas inside the workshop, when the air is discharged, the annular pipe 4 is opened. The annular pipe 4 transports the water flow to the atomizing head 401, and the water flow is converted into a mist by the atomizing head 401 and discharged into the first lower pipe 1. The fan 2 extracts the air inside the exhaust pipe 101, so that the air inside the first lower pipe 1 carries the water mist into the workshop to maintain the humidity of the air inside the workshop.

[0025] In this embodiment, a exhaust air pipe 101 is provided at the top of the first lower pipe 1. The exhaust air pipe 101 is installed at the bottom of the first lower pipe 1, and the fan 2 is located inside the exhaust air pipe 101.

[0026] During use, the air outside the workshop is transported to the exhaust air pipe 101 through the ventilation device 7. The fan 2 of the first lower pipe 1 extracts the air inside the exhaust air pipe 101, and the air is discharged into the workshop through the first lower pipe 1.

[0027] In this embodiment, a ventilation device 7 is provided on one side of the first lower pipe 1. The exhaust air pipe 101 is installed on one side of the ventilation device 7, and an intake pipe 801 is installed on the side of the ventilation device 7 away from the exhaust air pipe 101.

[0028] During use, the turbid air inside the workshop enters the intake pipe 801 through the intake grille 9, and the air passes through the intake grille 9 and is filtered by the filter element 901.

[0029] In this embodiment, a second lower pipe 8 is installed on one side at the bottom of the intake pipe 801. A plurality of electric push rods 803 are installed in the inner wall of the second lower pipe 8, and an intake grille 9 is installed at the bottom of the second lower pipe 8.

[0030] During use, long-term filtration causes the filter element 901 to become clogged, weakening the air flow. At this time, the staff activates the electric push rod 803, and the electric push rod 803 drives the intake grille 9 to move downward so that the intake grille 9 reaches a height that can be touched by the staff.

[0031] In this embodiment, the telescopic rod of the electric push rod 803 is installed at the bottom of the intake grille 9. Slide grooves 802 are respectively formed on both sides of the inner wall of the second lower pipe 8, and a clamping pipe 901 is installed at the top of the intake grille 9.

[0032] During use, the staff replaces the filter element 901 inside the clamping pipe 901, and activates the electric push rod 803 again. The electric push rod 803 drives the filter element 901 and the intake grille 9 to reset, facilitating the staff to replace the filter element 901 inside the intake pipe 801.

[0033] In this embodiment, the two outer sides of the clamping pipe 901 are clamped and connected inside the slide groove 802. A filter element 902 is installed inside the clamping pipe 901, and the bottom of the filter element 902 is attached to the top of the intake grille 9.

[0034] When in use, when the electric push rod 803 drives the engaging pipe 901 to descend, engaging blocks are arranged on both outer sides of the engaging pipe 901. The engaging blocks slide inside the sliding groove 802, and at the same time, the engaging blocks support the engaging pipe 901 through the sliding groove 802.

[0035] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: The air outside the factory building is transported into the exhaust pipe 101 through the ventilation device 7. The fan 2 of the first lower pipe 1 extracts the air inside the exhaust pipe 101, and the air is discharged into the factory building through the first lower pipe 1. In order to maintain the humidity of the gas inside the factory building, when the air is discharged, the annular pipe 4 is opened. The annular pipe 4 transports the water flow into the atomizing head 401, and the water flow is converted into a mist by the atomizing head 401 and discharged into the first lower pipe 1. The air inside the first lower pipe 1 carries the water mist into the factory building to maintain the humidity of the air inside the factory building. The turbid air inside the factory building enters the inside of the intake pipe 801 through the intake grille 9. The air passes through the intake grille 9 and is filtered by the filter element 901. However, long-term filtration causes the filter element 901 to be blocked, weakening the air fluidity. The second intake pipe 8 is installed in the ceiling interlayer, and the intake grille 9 is installed on the ceiling. At this time, the staff starts the electric push rod 803 inside the second lower pipe 8. The electric push rod 803 drives the intake grille 9 to move out of the ceiling, so that the intake grille 9 reaches a height that can be touched by the staff. The staff replaces the filter element 901 inside the engaging pipe 901. Then, the electric push rod 803 is started again. The electric push rod 803 drives the filter element 901 and the intake grille 9 to reset, which is convenient for the staff to replace the filter element 901 inside the intake pipe 801.
