Description

Technical Field

[0001] The present disclosure relates to the technical field of heat recovery equipment, and in particular to a horizontally installed heat recovery wheel mechanism. Background Art

[0002] The heat recovery wheel is used to transfer heat energy to the exhaust and supply air. It is usually installed vertically, that is, the upper and lower parts, or the left and right sides respectively transport indoor and outdoor air to recover heat energy. This installation method requires occupying the ground or indoor space.

[0003] Rotary heat exchangers are usually installed vertically, and the strength is generally guaranteed under the support frame. Sometimes, in order to save ground installation space, projects will use rooftop horizontal installation. Due to the heavy weight of the rotor itself, the strength of the support frame is insufficient when it is laid down. In order to meet the strength of the frame when the rotor is installed horizontally, the rotor frame is usually reinforced so that its center is still not deformed under the weight of the rotor. Utility Model Content

[0004] In order to solve the above problems, it is necessary to provide a horizontally installed heat recovery wheel mechanism, which can be applied to the horizontal installation of the heat recovery wheel without reinforcing the conventional wheel frame, and ensure that the wheel frame will not be deformed after installation and will not affect the normal operation of the heat recovery wheel.

[0005] According to one aspect of the present application, there is provided a horizontally installed heat recovery wheel mechanism, comprising a wheel frame and a wheel core; the wheel frame is connected to the wheel core via a connecting assembly so that the wheel frame is not affected by the gravity of the wheel core;

[0006] Wherein, the connecting assembly includes a fixed block and a stepped shaft, the fixed block is relatively installed on the wheel frame, and the stepped shaft is fixed between the fixed blocks by bolts; the wheel core is sleeved on the stepped shaft; and a lifting ring is provided on the fixed block.

[0007] In some embodiments, at least two of the hanging rings are provided, and the hanging rings are evenly distributed on the fixing block.

[0008] In some embodiments, the rotating wheel frame is further provided with a support frame for installing the motor, and belt tensioning units are provided on both sides of the motor support frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] As mentioned above, since only the wheel support frame is reinforced so that its center remains unchanged under the gravity of the heat recovery wheel, the reinforcement cost is low when the diameter and weight of the heat recovery wheel are small. When the wheel diameter is relatively large and the weight is heavy, the cost of reinforcing the frame to prevent it from deforming is high. Therefore, there is an urgent need for a horizontally installed heat recovery wheel mechanism that can be used for horizontal installation of the heat recovery wheel without reinforcing the conventional wheel frame, and ensures that the wheel frame does not deform after installation and does not affect the normal operation of the heat recovery wheel.

[0017] The application of the heat recovery wheel mechanism provided by the present invention in heat recovery equipment will be introduced below.

[0018] Figure 1 and Figure 3 The overall structural schematic diagram of the sample adding device according to the embodiment of the present disclosure is shown.

[0019] like Figure 1 As shown, the present disclosure provides a heat recovery wheel mechanism comprising a wheel frame and a wheel core; the wheel frame is connected to the wheel core through a connecting assembly so that the wheel frame is not affected by the gravity of the wheel core;

[0020] Wherein, the connecting assembly includes a fixed block and a stepped shaft, the fixed block is relatively installed on the wheel frame, and the stepped shaft is fixed between the fixed blocks by bolts; the wheel core is sleeved on the stepped shaft; and a lifting ring is provided on the fixed block.

[0021] Preferably, at least two lifting rings are provided, and the lifting rings are evenly distributed on the fixing block.

[0022] The technical solution of the present application is to set a lifting ring structure at the center of the wheel, and use the lifting ring structure to share the gravity of the wheel core to the lifting structure, thereby reducing the dependence on the strength of the wheel frame; at the same time, by setting a stepped shaft in the center of the wheel, it is prevented from moving downward when the wheel core is installed horizontally; in addition, tensioning mechanisms are set before and after the motor to prevent the belt from loosening and falling off as the running time increases; thereby, the wheel can be adjusted from a vertical installation to a horizontal installation without additionally increasing the strength of the wheel frame.

[0023] Example 1

[0024] Please refer to Figure 1 to Figure 5 The present invention discloses a horizontally installed heat recovery wheel structure, which includes a heat recovery wheel frame 1, a wheel core 2, a wheel core fixing block 3, a wheel step shaft 4, a wheel center sealing cover plate 5, a lifting ring 6, a motor support frame 7, a motor 8, a belt tensioning mechanism 9, and a belt 10.

[0025] Specifically, the center of the wheel frame 1 is designed to be supported in both horizontal and vertical directions. At the center of the frame, a wheel core fixing block 3 is provided at the top and bottom. Bolts are used to fix the wheel step shaft 4 to the wheel core fixing block 3, thereby fixing the wheel core 2 to the wheel frame 1.

[0026] The lower part of the runner step shaft 4 is designed with a step to prevent the runner wheel core 2 from sliding downward or shifting on the runner step shaft 4 when installed horizontally.

[0027] A threaded hole is provided on the side of the wheel core fixing block 3 for installing a lifting ring 6. The function of the lifting ring 6 is to lift the wheel core when installing it; it is also used for connection with other fixing mechanisms after installation. The weight of the runner core 2 is partially or fully borne by the lifting ring 6 and other fixing mechanisms. In this way, the gravity of the runner core 2 acting on the runner frame 1 is greatly reduced, or is completely borne by the lifting ring 6 and its fixing mechanism. The runner frame 1 does not bear the gravity of the wheel core 2, so that the runner frame does not deform.

[0028] The rotating wheel frame 1 is provided with a motor support frame 7 at its corner, the motor 8 lies on its side and is fixed on the motor support frame 7, the belt 10 is clamped on the rotating disk of the motor 8, and a belt tensioning mechanism 9 is provided at a suitable position where the belt 10 enters and is sent out of the rotating disk 11. The tensioning wheel of the belt tensioning mechanism 9 is H-shaped, so that the position where the belt 10 enters and is sent out of the rotating disk 11 is fixed, and the belt will not relax or slide down due to gravity.

[0029] The present invention provides a horizontally installed heat recovery wheel structure, which can change from standing ventilation to horizontal hanging ventilation without increasing the extra strength of the wheel frame; through the ring structure at the center of the wheel, the weight of the wheel can be borne by the ring and other fixed structures, so that the wheel frame is not subjected to stress, reducing the deformation of the frame, and thus there is no need to increase the strength of the frame; the tensioning structure before and after the wheel motor belt allows the wheel belt to always maintain the same tension, and at the same time, the H-shaped structure of the tensioning structure prevents the wheel belt from sliding down and falling off.
