Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas emission technology for testing centers, and specifically relates to an emission device for test exhaust gas from a testing center. Background Technology

[0002] The testing center generates a large amount of waste gas when conducting heat flow back pressure tests. The existing testing center does not have a dedicated exhaust device for waste gas discharge, and the testing site is limited, so the waste gas generated during the test cannot be automatically discharged outdoors.

[0003] Typically, axial flow fans are placed in the test center during testing to discharge exhaust gas. However, axial flow fans can only be used in test centers with short depths. When the depth is long, the exhaust gas can only be discharged from the test center to the other side, and it is impossible to discharge all the exhaust gas to the outside of the test center. At the same time, axial flow fans are large and heavy, which is not conducive to transportation. Therefore, there is an urgent need for a test center exhaust gas discharge device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an emission device for test waste gas in a testing center, in order to solve the problems mentioned in the background art.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figure 1 As shown, the present invention provides a test center exhaust gas emission device, comprising: a first trolley 1 and an axial flow fan 2 installed on the first trolley 1. The air outlet end of the axial flow fan 2 is provided with an exhaust mechanism for exhausting smoke. The exhaust mechanism includes an exhaust head 6, a high-temperature resistant folded hose 4 and a connector 3 connected in sequence. One end of the connector 3 is installed on the air outlet end of the axial flow fan 2. The exhaust head 6 extends to the outside of the test center through the high-temperature resistant folded hose 4.

[0023] As described above, using the first trolley 1, axial flow fan 2, and smoke exhaust mechanism provided by this utility model, the first trolley 1 facilitates the transport of the axial flow fan 2, thereby making it easy to bring the axial flow fan 2 to the predetermined position. Then, the smoke exhaust head 6 is taken to the outside of the test center. During this process, the high-temperature resistant folded hose 4 is unfolded, and when the axial flow fan 2 is started, the exhaust gas in the test center is discharged to the outside through the high-temperature resistant folded hose 4 and the smoke exhaust head 6.

[0024] In this utility model, combined with Figure 1 and Figure 3 As shown, a second trolley 9 for transporting the high-temperature resistant folded hose 4 is also provided on one side of the first trolley 1 in this embodiment. A first support column 7 is longitudinally installed on the top of the second trolley 9. A pipe clamp 5 is installed on the outer periphery between the high-temperature resistant folded hose 4 and the exhaust head 6 on the top of the first support column 7.

[0025] As described above, when using the second trolley 9 provided by this utility model, the exhaust head 6 is installed on the first support column 7 through the pipe clamp 5, so that when the second trolley 9 is moved, the exhaust head 6 can be moved to the predetermined position, thereby facilitating the unfolding and use of the folded high-temperature resistant flexible hose 4.

[0026] Furthermore, to facilitate the folding and storage of the high-temperature resistant flexible hose 4 on the second trolley 9, refer to... Figure 1 and Figure 4As shown, the top of the second trolley 9 is also equipped with an arc-shaped support plate 11 to support the high-temperature resistant folding hose 4. A second support column 8 for support is provided between the arc-shaped support plate 11 and the second trolley 9. When storing the high-temperature resistant folding hose 4, the high-temperature resistant folding hose 4 is directly folded and stored on the arc-shaped support plate 11, which makes it easy to fold and store the high-temperature resistant folding hose 4 on the second trolley 9, thereby facilitating the storage and transportation of the high-temperature resistant folding hose 4 by the second trolley 9.

[0027] Furthermore, to facilitate the removal of the exhaust nozzle 6 from the second trolley 9, refer to... Figure 5 As shown, the outer wall of the pipe clamp 5 is also provided with a plug rod 15 for connecting the first support column 7. The top of the first support column 7 is provided with a socket 16 for accommodating the plug rod 15. When the second trolley 9 cannot reach a position, the plug rod 15 can be pulled out from the socket 16, which will allow the pipe clamp 5 to detach from the first support column 7. The plug rod 15 can then be used to easily drive the exhaust head 6 to the predetermined position.

[0028] In this utility model, combined with Figure 2 As shown, the first trolley 1 in this embodiment is provided with a docking hole 14 on one side, the second trolley 9 is provided with a docking plate 13 inserted into the docking hole 14 on one side, and the top of the first trolley 1 is provided with a limiting member that restricts the docking plate 13 in the middle of the docking hole 14.

[0029] Combination Figure 2 As shown, the limiting component includes a T-shaped pin rod 10. The top of the first trolley 1 has a pin hole 12 that passes through the docking plate 13, and the pin rod 10 is movably inserted into the pin hole 12.

[0030] As described above, when using the limiting component, docking plate 13, and docking hole 14 provided by this utility model, and when it is necessary to move the axial flow fan 2 and the high-temperature resistant folded hose 4, the second trolley 9 is brought closer to the first trolley 1, and the docking plate 13 is inserted into the docking hole 14. At this time, the insertion holes on the first trolley 1 and the docking plate 13 are aligned, and one end of the pin rod 10 is inserted into the pin hole 12, thereby connecting the second trolley 9 to the first trolley 1. Thus, when the first trolley 1 is pushed, the second trolley 9 can be moved synchronously, which facilitates the movement and transportation of the axial flow fan 2 and the high-temperature resistant folded hose 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
