Description

Technical Field

[0001] The utility model relates to the technical field of support devices, and specifically relates to a support device for energy efficiency evaluation and performance testing of heat exchangers. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It plays an important role in many industrial productions such as chemical industry, petroleum, power, food and others. It is the main device for developing and utilizing industrial secondary energy, realizing waste heat recovery and energy conservation and emission reduction. The energy efficiency level of a heat exchanger can be obtained through thermal performance and fluid resistance performance tests, that is, the energy efficiency level of the heat exchanger is ultimately reflected by testing the heat exchange effects of high-temperature and low-temperature fluids at different flow rates. During the test process, on the heat source side and the cold source side, by connecting a relatively long test section to ensure that the fluid enters and exits the heat exchanger in a stable state, and at the same time, holes are opened on the test section to connect temperature and pressure measuring devices to achieve the function of stable measurement.

When the heat exchanger is fixed, during the process of testing the heat exchanger, the above technical solution can quickly fix the heat exchanger, but after the heat exchanger is fixed, the angle cannot be adjusted to a certain extent. Therefore, during the detection process, the outer wall of the heat exchanger cannot be observed in detail, and it is impossible to judge whether there are problems such as leakage in the heat exchange. Therefore, the above technical solution is relatively limited in use. For this reason, a support device for energy efficiency evaluation and performance testing of a heat exchanger is proposed.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0026] The following will describe the embodiments according to the overall structure of the present invention.

[0027] A support device for the energy efficiency evaluation and performance test of a heat exchanger, as Figures 1 to 5 shown, includes a base 1. A regulating mechanism 2 is fixedly connected to the top end of the base 1, and two sets of rotating mechanisms 3 are arranged at the top end of the regulating mechanism 2;

[0028] The rotating mechanism 3 includes a rotating shaft 301. A gear disk 303 is fixedly sleeved on the outer wall of the rotating shaft 301. The end of the rotating shaft 301 is fixedly connected to a contact disk 302. Rubber blocks are arranged on the side wall of the contact disk 302. Multiple groups of limiting heads 305 are meshed on the side wall of the gear disk 303. A set of sleeves 304 are respectively slidably sleeved on the outer walls of each group of limiting heads 305. One end of the limiting head 305 located inside the sleeve 304 is fixedly connected to a limiting spring 306. The end of the limiting spring 306 is fixedly connected to the inner wall of the sleeve 304. The sleeve 304 is fixedly connected to the position near the top end of the side wall of the sleeve rod 2062. The rotating shaft 301 is rotatably connected to the outer wall of the sleeve rod 2062, and the rotating shaft 301 is located in the middle of multiple sets of sleeves 304.

[0029] By driving the two sets of rotating mechanisms 3 to approach through the regulating mechanism 2, the contact disks on the two sets of rotating mechanisms 3 approach each other, so that the two contact plates drive the rubber blocks to clamp the heat exchanger. By pushing the heat exchanger, the heat exchanger drives the contact disk 302 to rotate. The contact disk 302 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the gear disk 303 to rotate, so that the gear disk 303 pushes the limiting head 305, so that the limiting head 305 is pushed by the tooth tip of the gear disk 303 to slide into the sleeve 304, thereby compressing the limiting spring 306. When a tooth tip of the gear disk 303 slides past the limiting head 305, the limiting spring 306 rebounds, so that the limiting head 305 resets. During the continuous rotation of the gear disk 303, the gear disk 303 and the limiting head 305 continuously repeat the above process, so that during the rotation of the gear disk 303, the resilience of the limiting spring 306 needs to be overcome, so that the rotating shaft 301 and the gear disk 303 are blocked by the limiting head 305 and cannot rotate without manual pushing, so that the heat exchanger will not rotate without manual pushing.

[0030] Please refer particularly to Figure 2 and Figure 3 , the adjusting mechanism 2 includes two groups of guide rails 201. The tops of the two groups of guide rails 201 are slidably connected with two groups of sliding plates 202. The two groups of sliding plates 202 are respectively close to the two ends of the two groups of guide rails 201. The bottom ends of each group of sliding plates 202 are respectively fixedly connected with a set of threaded sleeves 203. The inner walls of the two groups of threaded sleeves 203 are threadedly connected with a bidirectional threaded rod 204. The side wall of the base 1 is fixedly connected with a motor 205. The output end of the motor 205 is fixedly connected to the end of the bidirectional threaded rod 204. The top ends of each group of sliding plates 202 are respectively fixedly connected with a set of lifting components 206. The lifting component 206 includes a support rod 2061. The support rod 2061 is fixedly connected to the top end of the sliding plate 202. A sleeve rod 2062 is slidably sleeved on the outer wall of the support rod 2061. A chute 2063 is fixedly connected to the side wall of the sleeve rod 2062. A slider 2064 is slidably connected to the inner wall of the chute 2063. An electric push rod 2067 is fixedly connected to the side wall of the slider 2064. The end of the electric push rod 2067 is fixedly connected with a connecting block 2066. The top end and the bottom end of the connecting block 2066 are respectively hinged with a set of connecting plates 2065. The end of the upper set of connecting plates 2065 is hinged to the side wall of the sleeve rod 2062. The end of the lower set of connecting plates 2065 is hinged to the side wall of the support rod 2061.

[0031] The motor 205 drives the bidirectional threaded rod 204 to rotate, so that the bidirectional threaded rod 204 pushes the two groups of threaded sleeves 203 to approach each other. The threaded sleeves 203 drive the sliding plates 202 to slide on the tops of the guide rails 201, so that the two groups of sliding plates 202 respectively drive the two groups of lifting components 206 to approach each other. The two groups of lifting mechanisms respectively drive the two groups of rotating mechanisms 3 to approach each other. By contracting the electric push rod 2067, the connecting block 2066 is driven to approach the slider 2064, thereby pushing the two groups of connecting plates 2065, so that the two groups of connecting plates 2065 push the support rod 2061 and the sleeve rod 2062, so that the sleeve rod 2062 slides upward on the outer wall of the support rod 2061, thereby driving the chute 2063 and the rotating mechanism 3 to slide upward.

[0032] During use, through the relative movement of the two abutting plates, the abutting disc 302 abuts against the outer wall of the stove heat exchanger, thereby fixing the heat exchanger. Then, during the detection process, by pushing the heat exchanger, the rotating shaft 301 rotates, so that the angle of the heat exchanger can be conveniently adjusted, so that the heat exchanger can be displayed in front of the staff in a 360-degree manner, thereby facilitating the staff to observe the heat exchanger comprehensively and improving the comprehensiveness during the detection process. The parts not involved in this device are the same as or can be implemented by the prior art.
