If the number of the heat exchange pieces is not increased or decreased, the extrusion piece can be tightly pressed on the rear end plate again only by adjusting the extrusion piece in a small range after the steel bar is reset again, and compared with the mode that a nut needs to be screwed again along a long screw rod every time in the prior art, the installation and disassembly time is greatly saved.

Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a plate heat exchanger that is easy to disassemble. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchanger composed of a series of stacked, corrugated fins. Thin rectangular channels are formed between the fins, through which heat is exchanged. Plate heat exchangers are ideal for liquid-to-liquid and liquid-to-vapor heat exchange. They offer high heat transfer efficiency, minimal heat loss, a compact and lightweight structure, a small footprint, wide application, and a long service life.

[0003] During the installation process, multiple heat exchange fins need to be placed between the front and rear baffles, and then multiple screws are used to tighten the front and rear baffles so that the multiple heat exchange fins are close together. The number of heat exchange fins can be set arbitrarily according to actual needs. Therefore, the length of the screw is usually designed to be longer with a margin. During the installation process, the nut needs to be screwed into the screw at the end of the screw and tightened. Since the heat exchange fins need to be disassembled frequently, the nut needs to be re-screwed along the longer screw each time the nut is removed. The whole process takes a long time, and when the number of heat exchange fins is small, the leaking part of the screw will increase relatively, resulting in safety hazards. Utility Model Content

[0004] In view of the above problems, an embodiment of the present application provides a plate heat exchanger that is easy to disassemble, which can facilitate the quick disassembly of the heat exchange plate for cleaning and reduce the safety hazards caused by the excessive length of the screw.

[0005] According to one aspect of an embodiment of the present application, a plate heat exchanger that is easy to disassemble is provided. The cam is connected to the top of the support frame by the upper and lower limit switches, and the cam is connected to the support frame by the upper and lower limit switches, and the cam is connected to the support frame by the upper and lower limit switches.

[0006] In some embodiments, the extrusion member includes a plurality of support rods arranged on the side of the extrusion plate away from the rear end plate, and the other ends of the support rods are commonly connected to a threaded plate, and a second threaded rod is screwed and penetrated at the threaded plate, and one end of the second threaded rod penetrates and extends to the side of the extrusion plate close to the rear end plate and is connected to a rotating joint.

[0007] In some embodiments, the fastener includes a first support base provided at one end of the bottom side of the lower limit rod, and one end of the steel bar is detachably connected to the first support base.

[0008] In some embodiments, a second support base is provided at the bottom of the front end plate.

[0009] In some embodiments, a handrail disc is connected to the outer surface of the end of the first threaded rod turntable facing away from the steel bar.

[0010] In some embodiments, an auxiliary fixing rod is hinged to the top of the upper limit rod, and a clamping piece matching the armrest disc is fixed to the other end of the auxiliary positioning rod.

[0011] In some embodiments, a correction sleeve is connected to one side of the rigid bar, and the first threaded rod is arranged to pass through the correction sleeve.

[0012] The beneficial effects of the present application are as follows: in the present application, a steel bar is hinged on the upper limit rod and the steel bar is connected to the end of the lower limit rod through a fastener, and a first threaded rod, a support platform and an extrusion plate and other components are provided to cooperate with each other, so that when the heat exchange plate needs to be cleaned, there is no need to remove multiple nuts on the threaded rod one by one. It is only necessary to open the fastener and rotate the steel bar along the axis direction. At this time, the extrusion part and the extrusion plate and other components can be flipped upward with the steel bar, and the heat exchange plate can be easily disassembled. After the heat exchange plate is cleaned and reinstalled, if the number of heat exchange plates has not increased or decreased, after resetting the steel bar, only a small range of adjustment of the extrusion part is required to make the extrusion part tightly pressed on the rear end plate again. Compared with the prior art method of requiring the nut to be re-tightened along the longer screw rod every time, the installation and disassembly time is greatly saved.

The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0022] Specifically, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of a plate heat exchanger that is easy to disassemble provided in an embodiment of the present application. Figure 2This is a schematic diagram of the overall structure of the plate heat exchanger that is easy to disassemble during the disassembly process provided in an embodiment of the present application. Figure 3 This is a schematic diagram of the partial structure of the first threaded rod and its connection provided in an embodiment of the present application. Figure 4 for Figure 3Enlarged view at point A. The easily disassembled plate heat exchanger 100 includes a front plate 110, a rear plate 120, an upper stopper 130, and a lower stopper 140. These together form a frame for securing the heat exchange fins 150. As is well known, the front plate 110 should be provided with components such as water pipes for the flow of hot and cold media. Components such as the front plate 110 and the rear plate 120 can be configured in accordance with existing techniques and will not be further described here. The upper limit rod 130 and the lower limit rod 140 are jointly connected to the two sides of the front end plate 110 close to the rear end plate 120. A plurality of heat exchange plates 150 are jointly arranged between the upper limit rod 130 and the lower limit rod 140. The plurality of heat exchange plates 150 are located between the front end plate 110 and the rear end plate 120. The rear end plate 120 can be slidably connected between the upper limit rod 130 and the lower limit rod 140. The heat exchange plates 150 are clamped by the front end plate 110 and the rear end plate 120. The heat exchange plates 150 here are existing technology. The upper limit rod 130 and the lower limit rod 140 can be set with reference to the existing technology. The upper limit rod 130 and the lower limit rod 140 and the heat exchange plates 150 can be slidably connected through guide grooves, and the heat exchange plates 150 can be slidably installed along the guide groove direction. The upper and lower limiting rods 130 and 140 are connected to a movable fastening component 160 at their ends away from the front plate 110. The movable fastening component 160 is used to press the rear plate 120, so that the rear plate 120 further presses the plurality of heat exchange fins 150 against the front plate 110. The movable fastening component 160 includes two mounting platforms 161 symmetrically arranged at the ends of the upper limiting rod 130. A rotating shaft 162 is connected between the two mounting platforms 161. A steel bar 163 is hinged to the rotating shaft 162. One end of the steel bar can rotate around the central axis of the rotating shaft 162 and open after flipping upward. The bottom end of the steel bar is connected to the end of the lower limit rod 140 via a fastener 170. A first threaded rod 164 is threaded through the middle of the steel bar and is screwed at an angle. By rotating the first threaded rod 164, the support platform 165 can be pushed closer to or away from the rear end plate 120. After the first threaded rod 164 moves a certain distance, the multiple extrusion members 167 will move synchronously by the same distance, which can reduce the number of adjustments and the adjustment range of the extrusion members 167. The end of the first threaded rod 164 near the rear end plate 120 is connected to the support platform 165, and the other end of the support platform 165 is connected to the extrusion plate 166. The support platform 165 can be set at the geometric center point of the extrusion plate 166. The arrangement of the support platform 165 ensures that the pressure of the first threaded rod 164 can be more evenly applied to the extrusion plate 166. The extrusion plate 166 is provided with a plurality of extrusion parts 167 for lifting onto the rear end plate 120. The extrusion parts 167 are in various forms such as screws and inching screws. The extrusion parts 167 can provide thrust to the rear end plate 120, further enabling the rear end plate 120 to tightly cover the multiple heat exchange plates.

[0023] In the embodiment of the present application, during operation, when the heat exchanger 150 needs to be cleaned, the fastener 170 is opened and the steel bar is rotated around the rotating shaft 162. The free end of the steel bar drives the support platform 165, the first threaded rod 164, the extrusion plate 166, and the multiple extrusions 167 to flip upward and open as a whole. At this time, the extrusions 167 will move away from the rear end plate 120. The rear end plate 120 can then be slid along the upper limit rod 130 and the lower limit rod 140 and removed to remove the heat exchanger 150. During installation, it is only necessary to rotate the steel bar again, connect the fastener 170, and then press the extrusions 167 against the rear end plate 120 again.

[0024] As can be seen from the above, in the embodiment of the present application, a steel bar is hingedly connected to the upper limit rod 130 and the steel bar is connected to the end of the lower limit rod 140 through a fastener 170, and a first threaded rod 164, a support platform 165 and an extrusion plate 166 and other components are provided to cooperate, so that when the heat exchange plate 150 needs to be cleaned, there is no need to remove multiple nuts on the threaded rod one by one. It is only necessary to open the fastener 170 and rotate the steel bar along the direction of the rotating shaft 162. At this time, the extrusion piece 167 and the extrusion plate 166 and other components can be flipped upward with the steel bar, and the heat exchange plate 150 can be easily disassembled. After the heat exchange plate 150 is cleaned and reinstalled, if the number of heat exchange plates 150 has not increased or decreased, after resetting the steel bar, it is only necessary to adjust the extrusion piece 167 in a small range to make the extrusion piece 167 tightly pressed on the rear end plate 120 again. Compared with the prior art method of requiring the nut to be re-tightened along the longer screw rod each time, the installation and disassembly time is greatly saved.

[0025] In some embodiments, the extrusion member 167 includes a plurality of struts 167a disposed on the side of the extrusion plate 166 facing away from the rear end plate 120. The other ends of the struts 167a are collectively connected to a threaded plate 167b. A second threaded rod 167c is threadedly connected to and extends through the threaded plate 167b. One end of the second threaded rod 167c extends through and extends to the side of the extrusion plate 166 near the rear end plate 120, where it is then connected to a swivel joint. In this embodiment of the present application, after the support platform 165 is adjusted to a suitable position, the second threaded rod 167c can be rotated via the swivel joint, thereby causing the second threaded rod 167c to drive the swivel joint to abut against the rear end plate 120, completing the installation.

[0026] In some embodiments, the fastener 170 includes a first support base 171 disposed at one end of the bottom side of the lower limiting rod 140, and one end of the steel bar is detachably connected to the first support base 171. In the embodiment of the present application, the bottom end of the steel bar and the first support base 171 are screwed together using bolts, thereby ensuring connection strength while simplifying operation. In addition, the first support base 171 facilitates the overall grounding of the device.

[0027] In some embodiments, a second support base 180 is provided at the bottom of the front end plate 110. In the embodiment of the present application, by arranging the second support base 180 flush with the first support base 171, the entire device can be stably placed on the ground.

[0028] In some embodiments, a handrail disc 164a is connected to the outer surface of the end of the first threaded rod 164 that is away from the steel bar. In this embodiment of the present application, the handrail disc 164a is provided to facilitate the rapid rotation of the first threaded rod 164.

[0029] In some embodiments, an auxiliary fixing rod 190 is hingedly connected to the top of the upper limit rod 130. The other end of the auxiliary fixing rod is fixed to a clip that matches the armrest disc 164a. In the embodiment of the present application, by providing the auxiliary fixing rod 190, when the steel bar is flipped upward, the armrest disc 164a can be clipped into the clip. At this time, the steel bar is temporarily fixed and does not flip downward, making it easier for the operator to remove the heat exchange fin 150.

[0030] In some embodiments, a correction sleeve 168 is connected to one side of the rigid bar 163, and the first threaded rod 164 is disposed through the correction sleeve 168. In the embodiment of the present application, by providing the correction sleeve 168, when the first threaded rod 164 undergoes plastic deformation, the correction sleeve 168 can provide a certain degree of support and reduce deformation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
