The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] like Figure 1-3 The embodiment provided by the present invention is shown in FIG.

[0031] The embodiment of the present invention provides an exhaust device, including: a body 1, a blower 2 and a valve mechanism 3. The blower 2 can be a double-head blower. The blower 2 is arranged inside the body 1, and the valve mechanism 3 is arranged outside the body 1. The body 1 is provided with an air inlet channel 8 and an air outlet channel 9, respectively. The air inlet channel 8 and the air outlet channel 9 can be connected to the exhaust gas delivery pipeline respectively, so as to connect the body 1 in series to the exhaust gas delivery pipeline. The air inlet end of the blower 2 is connected to the air inlet channel 8, and the air outlet end of the blower 2 is connected to the air outlet channel 9. Specifically, an opening 14 connected to the outside is opened on the air inlet channel 8, and the valve mechanism 3 is connected to the opening 14, and can control the opening 14 to be connected to the outside or closed. In a specific implementation, the end of the air inlet channel 8 away from the blast device 2 can be connected to the exhaust gas generation point through the exhaust gas delivery pipe, and the end of the air outlet channel 9 away from the blast device 2 can be connected to the exhaust gas treatment point through the exhaust gas delivery pipe. Under normal circumstances, the valve mechanism 3 blocks the opening 14. When the blast device 2 is running, the exhaust gas at the exhaust gas generation point will be drawn into the exhaust gas delivery pipe by the blast device 2, and flow into the blast device 2 through the exhaust gas delivery pipe and the air inlet channel 8. Finally, driven by the blast device 2, the exhaust gas will flow along the exhaust channel 9 and the exhaust gas delivery pipe to the exhaust gas treatment point , after being harmlessly treated at the waste gas treatment point, it is discharged to the outside. Of course, according to actual production needs, the waste gas treatment point can also be an air dehumidification device; and when the waste gas treatment operation is completed, the valve mechanism 3 can movably open the opening 14. At this time, due to the greater resistance to gas flow in the waste gas delivery pipeline, the blower 2 will draw clean air from the outside through the opening 14, and discharge the waste gas in the air inlet channel 8, the blower 2 and the air outlet channel 9. The fast-flowing air can also take away moisture, so that the air inlet channel 8, the blower 2 and the air outlet channel 9 remain dry. In addition, a control cabinet 4 can be provided on one side of the fuselage 1. The control cabinet 4 is used to control the operation of the blower 2 and the valve mechanism 3 respectively. When the exhaust gas is discharged, the valve mechanism 3 blocks the opening 14 so that the blower 2 can draw the exhaust gas through the pipe connected to the air intake channel 8. When the exhaust gas treatment operation is completed, the control cabinet 4 will drive the valve mechanism 3 to open the opening 14. After the blower 2 has been running for a period of time, the control cabinet 4 will control the blower 2 to stop, and the ventilation and drying operation is completed, thereby avoiding part of the exhaust gas from stagnating inside the exhaust equipment, preventing the moisture and corrosive substances carried by the exhaust gas from continuously corroding the internal components of the exhaust equipment, and extending the service life of the exhaust equipment.

[0032] Specifically, the valve mechanism 3 includes a valve cover 31 and a driving member 32. The driving member 32 is a gas rod. The rear end of the gas rod is hinged on the fuselage 1. The telescopic end of the gas rod is hinged to the valve cover 31. The valve cover 31 is hinged to a side edge of the opening 14. The driving member 32 is connected to the valve cover 31 and can drive the valve cover 31 to flip and cover the opening 14. Under normal conditions, the telescopic end of the gas rod is extended to drive the valve cover 31 to flip and cover the opening 14. When the interior of the exhaust device needs to be dried and ventilated, the telescopic end of the gas rod will retract to drive the valve cover 31 to flip and open the opening 14. In another embodiment (not shown in the drawings), the valve mechanism 3 includes a telescopic cylinder and a cover plate. The telescopic cylinder is arranged on the fuselage 1 adjacent to the opening 14. The cover plate is arranged on the telescopic rod of the telescopic cylinder. The telescopic cylinder drives the cover plate to block the opening 14 or move away from the opening 14 by controlling the extension and contraction of the telescopic rod, thereby controlling the opening 14 to be opened or closed.

[0033] Furthermore, the air intake channel 8 includes an air intake cavity 11, an air intake pipe 21 and an air intake port 13. The air intake cavity 11 is located in the fuselage 1, and the air intake port 13 is opened on the side wall of the air intake cavity 11 for communicating with the exhaust gas conveying pipeline. The opening 14 is arranged on the inner wall of the other side of the air intake cavity 11, and the two ends of the air intake pipe 21 are respectively connected with the air intake cavity 11 and the air inlet end of the blowing device 2; the air outlet channel 9 includes an air outlet cavity 12, an air outlet pipe 22 and an air outlet 15. The air outlet cavity 12 is located in the fuselage 1, and the air outlet 15 is opened on the side wall of the air outlet cavity 12 for communicating with the exhaust gas conveying pipeline. The two ends of the air outlet pipe 22 are respectively connected with the air outlet cavity 12 and the air outlet end of the blowing device 2. Specifically, one end of the exhaust gas conveying pipe away from the exhaust gas generation point is connected to the air inlet 13, and the other end of the exhaust gas conveying pipe away from the exhaust gas treatment point is connected to the air outlet 15. When the blowing device 2 is operating, the exhaust gas will flow through the exhaust gas conveying pipe, the air inlet 13, the air inlet cavity 11, the air inlet pipe 21, the blowing device 2, the air outlet pipe 22, the air outlet cavity 12, the air outlet 15, the exhaust gas conveying pipe in sequence, and finally discharged to the exhaust gas treatment point.

[0034] Specifically, one end of the air inlet pipe 21 connected to the air inlet cavity 11 is located on the side wall of the air inlet cavity 11 and is spaced apart from the bottom wall of the air inlet cavity 11 in the vertical direction; one end of the air outlet pipe 22 connected to the air outlet cavity 12 penetrates the bottom wall of the air outlet cavity 12 from bottom to top and partially extends into the air outlet cavity 12. The extended portion of the air outlet pipe 22 can play a water-blocking role to prevent the accumulated water condensed by water vapor in the air outlet cavity 12 from flowing back into the interior of the blowing device 2 through the air outlet pipe 22, so as to avoid affecting the normal operation of the blowing device 2. The settings of the air inlet cavity 11 and the air inlet pipe 21 are similar.

[0035] Furthermore, two air outlets 15 are provided, one air outlet 15 is arranged on the top wall of the air outlet cavity 12, and the other air outlet 15 is arranged on a side wall of the air outlet cavity 12. The two air outlets 15 can take into account the connection of exhaust gas conveying pipes in different directions. When in use, it is only necessary to connect the exhaust gas conveying pipe to one of the opposite air outlets 15, and then seal the other air outlet 15, so as to improve the applicability of the exhaust equipment.

[0036] Specifically, a receiving chamber 16 for accommodating the blowing device 2 is further provided in the fuselage 1. The receiving chamber 16 is located below the air inlet chamber 11 and the air outlet chamber 12. The longitudinal distribution can reduce the occupation of the production site area by the exhaust equipment.

[0037] Furthermore, an air intake drain pipe 51 and an air outlet drain pipe 52 are respectively provided in the accommodating chamber 16. One end of the air intake drain pipe 51 passes through the bottom wall of the air intake chamber 11 and is connected to the air intake chamber 11. One end of the air outlet drain pipe 52 passes through the bottom wall of the air outlet chamber 12 and is connected to the air outlet chamber 12. Both the air intake drain pipe and the air outlet drain pipe 52 can be connected to a collection point through a hose. After the exhaust equipment extracts exhaust gas with high humidity, water is easily accumulated at the bottom of the air intake chamber 11 and the air outlet chamber 12. At this time, the user can open the valves on the air intake drain pipe 51 and the air outlet drain pipe 52 to discharge the accumulated water in the air intake chamber 11 and the air outlet chamber 12 through the hose to the collection point for treatment, so as to avoid the accumulation of water affecting the normal use of the exhaust equipment.

[0038] Furthermore, a protective cover 6 is provided on the outer wall of the fuselage 1, and the protective cover 6 is enclosed outside the opening 14 and the valve mechanism 3. A ventilation port 61 is provided on the protective cover 6, and a protective net 7 is installed at the ventilation port 61. The protective cover 6 and the protective net 7 can prevent foreign objects from knocking against the valve mechanism 3, and prevent debris from falling into the air intake chamber 11 through the opening 14 to affect the normal use of the exhaust equipment. When the exhaust equipment is ventilated, outside air can enter the protective cover through the protective net 7, and then flow into the air intake chamber 11 through the opening 14.

[0039] Furthermore, two inlet pipes 21 and two outlet pipes 22 are provided, corresponding to the double-headed blower selected as the blower 2. The two inlet pipes 21 are arranged in one-to-one correspondence with the two air inlet ends of the double-headed blower, and the two outlet pipes 22 are arranged in one-to-one correspondence with the two air outlet ends of the double-headed blower, so that the generated air volume is nearly doubled under the condition of similar energy consumption to the single-headed blower, thereby improving the efficiency of exhaust gas emission and ventilation and improving economic benefits. Specifically, the volute of the blower 2 is made of aluminum alloy and has been treated with electrophoresis corrosion protection, so that the service life is longer. The motor of the blower 2 is a permanent magnet motor, the impeller is a three-dimensional flow impeller, and is equipped with a vector inverter. By combining the vector inverter, the permanent magnet motor and the three-dimensional flow impeller, the vector inverter is used to control the permanent magnet motor to work efficiently at a high speed, so that efficient air supply operation can be achieved within the wind pressure range of 1-40kpa, which widely makes up for the low working efficiency of the axial flow fan in this wind pressure range, and truly achieves the purpose of environmental protection and energy saving.
