Description

Technical Field

[0001] The utility model relates to the technical field of box-type heat exchange stations, in particular to a box-type heat exchange station which can be quickly disassembled and assembled. Background Art

[0002] The box heat exchange station is a key equipment for large-scale thermal engineering projects such as urban heating, air conditioning and refrigeration. Its functions are mainly reflected in three aspects: heat energy transfer, energy efficiency optimization and temperature regulation. Through the core component heat exchanger, the box heat exchange station realizes efficient heat transfer between the heat source and the cooling fluid, ensuring the effective use of energy in the system. Its structure includes heat exchangers, valves and control systems, brackets and shells, inlet and outlet pipes and other components. Through the synergistic effect of these components, precise regulation of fluid temperature and flow control can be achieved. The working principle is based on the heat exchange process, in which the control system monitors parameters such as temperature and pressure, and adjusts valves to maintain stable operation of the system. For example, the authorization announcement number CN213178559U discloses a box-type heat exchange station body and a box-type heat exchange station that can be quickly disassembled and assembled. The heat exchange station body includes a bottom plate, vertical beams, corner tees, side beams, cross beams, wall panels, door wall panels and top plates. Vertical beams are arranged on the four corners of the top of the bottom plate. The top end of each vertical beam is connected to the side beams and cross beams through a corner tee. Wall panels and door wall panels are arranged between the side beams and the cross beams and the bottom plate. Multiple top plates are arranged between the two cross beams and the two side beams. It changes the structure and installation process of the box-type heat exchange body, thereby changing the installation process of the box-type heat exchange station, without the need to install the heat exchange station equipment. The whole is pushed into the heat exchange station box. However, in this technical solution, when constructing, it is necessary to first assemble various heat exchange equipment and water treatment equipment on the bottom plate. The entire box can only be arranged after the various treatment equipment is arranged. This means that the box station needs to be carried out on site. The reason is that it is difficult to load heat treatment equipment into the prefabricated box station, and it is difficult to prefabricate in the factory. It is necessary to wait for the on-site assembly and commissioning of various equipment. The construction period of the entire box station will be relatively long, which not only increases the investment cost of the project, but also delays the completion time of the project. Compared with factory prefabrication, on-site assembly is restricted by factors such as on-site environment and construction conditions, and is easily affected by human factors and external factors, resulting in instability and difficulty in control of construction quality.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 The utility model provides an embodiment: a box-type heat exchange station that can be quickly disassembled and assembled, comprising a box-type station body 1 and a bottom frame 2 fixed at the bottom of the box-type station body 1, a table 3 is installed on the top of the bottom frame 2 through a sliding anti-detachment structure, and a heat treatment device 5 is arranged on the top of the table 3, and a rectangular cut-out groove 301 that completely penetrates the table 3 is arranged on the surface of the table 3;

[0019] A main transmission shaft 7 is rotatably installed inside the bottom frame 2 through a bearing seat, and both ends of the main transmission shaft 7 are installed with a gear rack pushing structure 8 for driving the table plate 3 to translate in the Y-axis direction. A vertical shaft 9 is rotatably installed on one side of the bottom of the bottom frame 2, and a right-angle bevel gear transmission structure 10 is arranged between the vertical shaft 9 and the main transmission shaft 7. A worm gear self-locking unit for driving the vertical shaft 9 to rotate is installed on the back of the box-type station body 1, and a motor controller 4 electrically connected to the input end of the worm gear self-locking unit is installed on the inner wall of one side of the box-type station body 1. The staff turns on the stepper motor 12 through the motor controller 4 to work, and the rotational power of the stepper motor 12 is transmitted to the main transmission shaft 7 through the worm gear transmission structure 11, the vertical shaft 9 and the right-angle bevel gear transmission structure 10 in turn. At this time, the main transmission shaft 7 drives the table plate 3 to move forward through the gear rack pushing structure 8, so that the table plate 3 is misaligned with the bottom frame 2, until the table plate 3 moves out of the area outside the box-type station body 1 enough for the heat treatment equipment 5 to be installed;

[0020] A rectangular slot 101 is provided on the surface of the box-type station body 1, and an internal threaded hole 102 is provided on the surface of the box-type station body 1 on one side of the rectangular slot 101. A front door panel 6 is provided on the surface of the box-type station body 1, and a rectangular insert that is plugged into the rectangular slot 101 is provided on the back of the front door panel 6. When the heat treatment equipment 5 is assembled stably, the staff takes out the front door panel 6, so that the rectangular insert on the back of the front door panel 6 is docked into the rectangular slot 101, and then the internal threaded hole 102 is tightened with a bolt. At this time, the box-type station body 1 is in a closed state;

[0021] After the box-type station body 1 is prefabricated in the factory, the box-type station body 1 can be assembled and debugged in the factory, reducing on-site construction time and manpower investment, reducing construction costs, and factory prefabrication can be carried out in a controlled environment, reducing the influence of human factors and the external environment, which is conducive to improving the quality stability and reliability of the product and reducing the instability and difficulty of control of construction quality;

[0022] The sliding anti-slip structure includes a guide rail 201 fixed to the top of the bottom frame 2, and a slider 202 fixed to the bottom of the table 3. The slider 202 and the guide rail 201 are slidably matched. When the table 3 is driven to slide out, the bottom of the table 3 slides with the guide rail 201 through the slider 202. The guide rail 201 and the slider 202 can reduce the vibration and noise during the movement of the table 3.

[0023] The worm gear self-locking unit includes a stepper motor 12 installed on one side of the back of the box-type station body 1, and a worm gear transmission structure 11 installed at the output end of the stepper motor 12 for driving the vertical shaft 9 to rotate;

[0024] The gear rack pushing structure 8 includes helical gears fixed on both ends of the surface of the main transmission shaft 7 and helical racks fixed on both sides of the bottom end of the table 3. The helical racks and the helical gears are meshed with each other. The rotational power of the stepper motor 12 is transmitted to the worm, and the worm drives the vertical shaft 9 to rotate through the worm gear, and the main transmission shaft 7 drives the helical rack to move through the active gear. At this time, the helical rack drives the table 3 to move together. The design of the gear and rack can withstand greater force and torque, and is suitable for carrying heavier table 3 and equipment.

[0025] When the embodiment of the present application is in use, first, the staff prefabricates the box-type station body 1 in the factory, so that the box-type station body 1 is a box structure. When the box is transported to the site for hoisting and loading of the heat treatment equipment 5, the staff turns on the stepper motor 12 through the motor controller 4 to work, and the rotary power of the stepper motor 12 is transmitted to the main transmission shaft 7 through the worm gear transmission structure 11, the vertical shaft 9 and the right-angle bevel gear transmission structure 10 in turn. At this time, the main transmission shaft 7 drives the table plate 3 forward through the gear rack pushing structure 8, so that the table plate 3 and the bottom frame 2 are misaligned. In this process, the sliding anti-slip structure at the top of the bottom frame 2 makes the bottom frame 2 and the table plate 3 stable. A fixed sliding fit is performed until the table plate 3 moves out of the outside of the box-type station body 1 to an area sufficient for the installation of the heat treatment equipment 5. During this process, the rack and pinion sliding structure 8 can ensure the smooth movement of the table plate 3, and the worm gear transmission structure 11 has a self-locking function, which can achieve more precise control. In conjunction with the drive of the stepper motor 12, the moving position and speed of the table plate 3 can be accurately controlled to ensure the stability and accuracy of the table plate's movement. As a result, after the box-type station body 1 is prefabricated in the factory, the staff can still install and combine various equipment on the table plate 3, realize standardization of production and assembly line operation, improve production efficiency, and reduce labor and time costs.
