Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an energy-saving heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization.

[0003] When the heat exchanger is in use, due to its large size and weight, it needs to be installed on the bracket with the help of a crane. However, there is no precise guide structure to assist in the placement of the crane during the crane installation, so the on-site staff needs to manually assist the crane to position it. This method uses the staff to visually judge whether the position is accurate, and there will be large errors. Due to the error, when the heat exchanger is installed on the bracket, its outer wall will hit the corner of the bracket, causing the outer wall of the heat exchanger to be worn, thereby damaging the protective layer of its outer wall.

[0004] Therefore, the present application provides an energy-saving heat exchanger to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an energy-saving heat exchanger to solve the problem that the existing guiding mechanism can quickly assist the hoisting machine in installing the heat exchanger. It can not only quickly guide the heat exchanger, but also buffer the heat exchanger, effectively preventing the problem of scratches caused by collision when the heat exchanger contacts the bracket. Through the flexible use of the structure, the vibration generated during use can be reduced to prevent the connection of the heat exchanger from loosening due to the influence of long-term vibration.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] An energy-saving heat exchanger comprises a bracket body, wherein a mounting groove is provided in the bracket body, a mounting block is equidistantly fixedly connected to the bottom of the bracket body, and first weakened grooves are provided on both side outer walls of the bracket body; a guide mechanism is used to assist the installation of the heat exchanger, and the guide mechanism is connected to the bracket body.

[0008] Optionally, the guide mechanism comprises a guide plate fixedly mounted on the top of the bracket body, a first buffer cavity is opened on the top of the guide plate on one side of the bracket body, and a second buffer cavity is opened at an equidistant distance on the top of the guide plate.

[0009] Optionally, the outer walls on both sides of the bracket body are provided with slots adapted to the shape of the bottom of the guide plate, and the bottom of the guide plate is inclined at an angle of thirty degrees.

[0010] Optionally, the cross-section of the guide plate is M-shaped, a first weakening groove is provided on the guide plate, the cross-section of the first buffer cavity is triangular, and the cross-section of the second buffer cavity is elliptical.

[0011] Optionally, a support plate is installed on the bracket body, the support plate is made of steel, and a rubber pad is fixedly connected to the top outer wall of the support plate.

[0012] Optionally, the support plate is corrugated, and the corrugations thereof become sparser from top to bottom, and movable blocks are fixedly connected to the bottom of the support plate in an annular manner at equal intervals.

[0013] Optionally, the bottom center point of the movable block is fixedly connected to the bracket body.

[0014] Optionally, second weakening grooves are provided on both sides of the movable block.

[0015] Optionally, movable grooves are equidistantly provided in an annular shape at the bottom of the bracket body, the openings of the movable grooves are adapted to the shape of the movable block, the cross-sectional area of ​​the bottom of the movable grooves is larger than the cross-sectional area of ​​the bottom of the movable block, the outer wall edge of the movable grooves is arc-shaped, and the outer wall of the movable grooves is provided with anti-slip grooves.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up a guiding mechanism, the installation of the heat exchanger by the hoisting machine can be quickly assisted. It can not only quickly guide the heat exchanger, but also buffer the heat exchanger, effectively preventing the problem of scratches caused by collision when the heat exchanger contacts the bracket. Through the flexible use of the structure, the vibration generated during use can be reduced to prevent the connection of the heat exchanger from loosening due to long-term vibration.

[0018] A guide plate is arranged in the guide mechanism, the guide plate is located on both sides of the top of the bracket body, and the guide plate is M-shaped. When in use, the top of the guide plate first cooperates with the first buffer cavity and the second buffer cavity to accurately guide the heat exchanger while buffering the downward impact force. When the impact force is too large, the guide plate as a whole is deformed to further improve the buffering capacity of the guide plate. The structure makes the use of the guide mechanism better.

[0019] A support plate is provided in the bracket body, and the heat exchanger is placed on the support plate with the guidance of the guide plate. When the heat exchanger is installed on the support plate, the support plate can further buffer the heat exchanger through corrugation changes, and the support plate and the movable block are integrally constructed. During this period, the support plate is squeezed into the movable groove by the force at the connection between the bottom of the movable block and the bracket body, and in actual use, the top outer wall of the movable block and the top inner wall of the movable groove are affected by the vibration of the heat exchanger, and the movable block is deformed. Through the interaction between the restorative force and the friction force of the movable block, the device can have better practicality.

[0020] In summary, through the coordinated use of the guide mechanism and the support plate, the downward pressure generated during the impact is utilized to cause the guide plate to deform to achieve a buffering effect, and the corrugation transformation of the support plate itself further allows the heat exchanger to enter the storage slot of the bracket body and be buffered. In addition, through the interaction between the support plate and the movable block fixedly connected to its bottom, the vibration generated during use can also be efficiently reduced. During the entire use of the device, no manual auxiliary operation is required, which not only saves manpower but also makes the device more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figures 1 to 5 As shown, an embodiment of the utility model provides an energy-saving heat exchanger, including a bracket body 1, wherein a mounting groove is provided in the bracket body 1, a mounting block 2 is equidistantly fixedly connected to the bottom of the bracket body 1, and first weakened grooves 6 are provided on both sides of the outer wall of the bracket body 1; a guide mechanism, the guide mechanism is used to assist in the installation of the heat exchanger, the guide mechanism is connected to the bracket body 1, the top of the second buffer cavity 5 is fixed to the top of the bracket body 1, the bottom of the second buffer cavity 5 is inserted into the slot 11, the top of the support plate 7 is fixed to the top of the bracket body 1, the bottom of the support plate 7 is in contact with the inner wall of the bracket body 1 but not connected, the support plate 7 is both rigid and flexible, and it can produce deformation and can also heat exchange The guide plate 3 in the guide mechanism can quickly guide the installation of the heat exchanger. During use, the top of the guide plate 3 first contacts the outer wall of the heat exchanger, and the first buffer chamber 4 and the second buffer chamber 5 in it respectively have different buffering effects on the heat exchanger, effectively preventing the heat exchanger from colliding and scratching at the moment of contacting the guide plate 3. Therefore, even if the volume and weight are large, there is no precise guide structure to assist the placement of the guide plate 3 during crane hoisting, and there is no need for on-site staff to manually assist the crane to position it, and there is no need for staff to visually judge whether the position is accurate, and the heat exchanger will not be difficult to install due to errors. When installed on the bracket, the outer wall will not hit the corners of the bracket, causing the outer wall of the heat converter to be worn. When the structures are used in combination, the device has good guidance and buffering properties.

[0036] like Figures 1 to 5As shown, the guide mechanism includes a guide plate 3 fixedly mounted on the top of the bracket body 1, a first buffer cavity 4 is provided on the top of the guide plate 3 on one side of the bracket body 1, and a second buffer cavity 5 is equidistantly provided on the top of the guide plate 3; slots 11 adapted to the shape of the bottom of the guide plate 3 are provided on the outer walls of both sides of the bracket body 1, and the bottom of the guide plate 3 is inclined at an angle of thirty degrees; the cross-section of the guide plate 3 is M-shaped, a first weakening groove 6 is provided on the guide plate 3, the cross-section of the first buffer cavity 4 is triangular, and the cross-section of the second buffer cavity 5 is elliptical. By distinguishing the shapes of the first buffer cavity 4 and the second buffer cavity 5, the first buffer cavity 4 and the second buffer cavity 5 can have different buffering effects. The first buffer cavity 4 is a stable triangle, Therefore, the strength of the first buffer chamber 4 is higher, so that when the first buffer chamber 4 is first released from the heat exchanger, its support will not be affected by excessive deformation, and when the impact force is too large during the process, the guide plate 3 will be deformed, which has a further buffering effect. The deformation at the first weakened groove 6 on the guide plate 3 is particularly obvious. During the entire buffer guiding process, the angle between the inclined surface formed at the upper end of the guide plate 3 and the horizontal plane is always greater than fifteen degrees. Since the guide plate 3 is always subjected to a downward force, the bottom of the guide plate 3 is inserted into the slot 11 by insertion without loosening or falling off. The inclination of the bottom of the guide plate 3 makes the guide plate 3 better in support, and the structure makes the guiding mechanism more perfect and more convenient to use.

[0037] like Figures 1 to 5As shown, a support plate 7 is installed on the bracket body 1, and the support plate 7 is made of steel, and a rubber pad is fixedly connected to the top outer wall of the support plate 7; the support plate 7 is corrugated, and its corrugation becomes sparse from top to bottom, and a movable block 9 is fixedly connected to the bottom of the support plate 7 in an equidistant manner; the movable block 9 is concave, and the bottom center point of the movable block 9 is fixedly connected to the bracket body 1; a second weakening groove 10 is provided on both sides of the movable block 9; movable grooves 8 are equidistantly provided in an annular manner at the bottom of the bracket body 1, and the opening of the movable groove 8 is adapted to the shape of the movable block 9, and the cross-sectional area of ​​the bottom of the movable groove 8 is larger than the cross-sectional area of ​​the bottom of the movable block 9, and the outer wall edge of the movable groove 8 is arc-shaped, and the outer wall of the movable groove 8 is provided with anti-slip grooves, through the use of steel, the hardness of the steel itself is utilized to and its ductility, the support plate 7 can produce a certain deformation when it is under pressure, and the corrugated structure of the support plate 7 can reduce the contact surface between the support plate 7 and the heat exchanger, and can reduce the friction between the heat exchanger and the support plate 7, so that the heat exchanger can be affected by gravity and slide quickly and smoothly to the center position of the support plate 7, and the bottom of the movable block 9 is fixedly connected to the bracket body 1 to limit the movable block 9, so that when vibration occurs during the operation of the sub-ah, the support plate 7 and the movable block 9 are ensured not to separate from the bracket body 1, and the support plate 7 and the movable block 9 are deformed, resulting in the rapid conversion of the restoring elastic force of the support plate 7 and the movable block 9 and the friction generated by the movable groove 8 and the support plate 7, so as to achieve a good vibration reduction effect, and the structure is simple, the use effect is good, and the practicality of the device is further improved.

[0038] The working principle of the technical solution provided by the utility model is as follows: when in use, first place the bracket body 1 on a horizontal working surface. Then fix the bracket body 1 to the working surface through the mounting block 2. Then hoist the heat exchanger by a crane. During the working process, the heat exchanger is roughly aligned with the center position of the upper end of the guide plate 3 by the crane. Then the crane slowly hoists the heat exchanger downward. When the heat exchanger is about to contact the guide plate 3, the descending speed of the heat exchanger is further reduced so that the heat exchanger and the top of the guide plate 3 are first contacted. The first buffer chamber 4 and the second buffer chamber 5 perform the first step of buffering for the heat exchanger. The inclined surface at the top of the guide plate 3 guides the heat exchanger to the center position of the support plate 7, and at the same time prevents the heat exchanger from seriously colliding with the guide plate 3 and causing surface scratches. When the collision force is large, first, after the first buffer chamber 4 and the second buffer chamber 5 complete the buffering, the first weakening groove 6 is deformed to produce further buffering effect. Then the guide plate 3 guides the heat exchanger to the support plate 7, and the support plate 7 guides the heat exchanger to the center of its upper end through its corrugated inclined surface structure. The lower end of the guide plate 3 is set in the slot 11, and all the downward forces applied to the guide plate 3 make it stably set in the slot 11 without falling off. When in use, the heat exchanger is placed on the support plate 7, and the bottom of the movable block 9 is connected to the bracket body 1. When vibration occurs, the support plate 7 and the movable block 9 are deformed by the vibration. The top outer wall of the movable block 9 and the inner wall of the movable groove 8 produce strong friction. The rapid conversion of the negative elastic force generated by the friction force and the deformation can achieve a good vibration reduction effect, so that the device not only has good guidance when in use, but also does not require the assistance of staff to install. And its good vibration reduction effect prevents the device from loosening or falling off during long-term use, allowing the device to always maintain stable operation, and the structure also improves the working efficiency of the device to a certain extent.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
