Description

Technical Field

[0001] The utility model relates to the technical field of plate type radiators, in particular to a fixing structure for a plate type heat exchanger. Background Art

[0002] Plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. Under the same pressure loss conditions, its heat transfer coefficient is 3-5 times higher than that of tube heat exchanger, and the floor space is one-third of that of tube heat exchanger.

[0003] According to the announcement number: CN209558969U, a plate heat exchanger is disclosed, including a plate assembly, the plate assembly includes a plurality of plates, each plate is provided with a first flow channel and a second flow channel on both sides, the cross-sectional area of ​​the first flow channel is larger than the cross-sectional area of ​​the second flow channel, the first flow channels between adjacent plates are combined to form a wide flow channel for connecting the cold medium, and the second flow channels between adjacent plates are combined to form a narrow flow channel for connecting the hot medium. The utility model can not only reduce the flow resistance of the large flow fluid, but also maintain the flow rate of the small flow fluid by arranging the wide flow channel and the narrow flow channel in the plate assembly to connect the large flow cold medium and the small flow hot medium, so as to ensure that the heat exchange efficiency of the plate heat exchanger is not reduced, and meet the heat exchange requirements of the heating industry. At the same time, due to the large cross-sectional area of ​​the wide flow channel, it can be applied to media with high viscosity and containing particles.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the flow rates on both sides of the plate heat exchanger are unequal and the difference is large, in order to reduce the flow resistance of the large flow, the number of channels will be satisfied by increasing the plates, so that the number of channels and the cross-sectional area of ​​the channels through which the large and small flows pass will be the same, thereby making the flow rate of the small flow medium lower, thereby causing the heat exchange efficiency to decrease and unable to meet the heating requirements. Or different process combinations are used to make the flow rates of the two media as close or equal as possible, but in the case of multiple processes, the flow resistance increases, the pressure drop is large, and the operating cost is high.

[0005] However, in actual use, the heat exchange plates need to be disassembled and cleaned. Since the existing plate fixing method is usually fixed together by a clamp or a pressure plate through bolts to form a frame structure, in order to ensure the stability of the plate, multiple bolts are often used for fixing. Then, when disassembling, it causes cumbersome disassembly for the operator and reduces work efficiency. For this reason, we provide a new fixing structure for plate heat exchangers.

Since the existing plate fixing method is usually fixed together by bolts through a clamp or a pressure plate to form a frame structure, in order to ensure the stability of the plate, multiple bolts are often used for fixing. As a result, when disassembling, the operator suffers from cumbersome disassembly and reduces work efficiency.

DETAILED DESCRIPTION

[0023] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0024] like Figures 1 to 4 As shown, the utility model provides a fixing structure for a plate heat exchanger, comprising a front plate 1, a plate 2 and a rear plate 3, the plate 2 being located on the back of the front plate 1, a plurality of plates 2 being arranged and being distributed at equal distances, the top and bottom of the front side of the rear plate 3 being fixedly connected with guide rods 4, the other end of the guide rod 4 being fixedly connected with the back side of the front plate 1, guide grooves 5 being provided on the top and bottom of the plate 2, the plate 2 being slidably connected to the surface of the guide rod 4 through the guide grooves 5, the surface of the guide rod 4 being slidably connected with a movable splint 6, the back side of the movable splint 6 being fixedly connected with a moving component 7, and the front side of the movable splint 6 being fixedly installed with a limiting component 8 through a slot hole.

[0025] refer to Figure 3 The moving component 7 includes an electric cylinder 71, which is fixedly connected to the back of the movable splint 6. There are four electric cylinders 71 distributed at the four corners of the back of the movable splint 6. The left and right sides of the surface of the electric cylinder 71 are fixedly connected with mounting components 72.

[0026] As a technical optimization scheme of the present invention, a moving mechanism is set up, so that the electric cylinder 71 is fixedly installed with the rear plate 3 through the installation component 72, and then the output end of the electric cylinder 71 is fixedly installed with the plate 2. When the operator needs to fix the plate 2, the operator starts the electric cylinder 71, and then the electric cylinder 71 drives the movable splint 6 to move toward the plate 2, so that the movable splint 6 is pressed against the plate 2, thereby completing the installation, thereby improving the convenience of the operator to fix the plate 2. At the same time, the electric cylinders 71 arranged at the four corners can well ensure that the force at each position of the movable splint 6 is uniform. When the operator needs to disassemble the plate 2, the operator controls the output end of the electric cylinder 71 to retract, so that the movable splint 6 no longer presses against the plate 2, so that the operator can easily disassemble the plate 2.

[0027] refer to Figure 3 and Figure 4 The limit assembly 8 includes a pressure sensor 81, which is fixedly installed on the front of the movable splint 6 through a slot. Four pressure sensors 81 are provided and distributed at the four corners of the front of the movable splint 6. A controller 82 is fixedly connected to the back of the rear plate 3. The pressure sensor 81 is electrically connected to the controller 82 through a wire, and the electric cylinder 71 is electrically connected to the controller 82 through a wire.

[0028] As a technical optimization scheme of the utility model, by setting a limit component 8, the operator can set the maximum force threshold of the plate 2 inside the controller 82. When the movable splint 6 presses the plate 2 through the electric cylinder 71, the pressure sensor 81 transmits the pressure value to the inside of the controller 82 through a wire. When the set threshold is reached, the controller 82 turns off the electric cylinder 71 to prevent the electric cylinder 71 from continuously applying pressure and causing damage to the plate 2.

[0029] refer to Figure 3 The mounting assembly 72 includes a mounting block 721, which is fixedly connected to the left and right sides of the surface of the electric cylinder 71. The mounting block 721 and the rear plate 3 are both provided with threaded holes 722, and the internal threads of the threaded holes 722 are connected with screw rods 723.

[0030] As a technical optimization solution of the utility model, by setting the installation component 72, when the operator needs to install the electric cylinder 71, the operator picks up the electric cylinder 71 to drive the installation block 721 to move, and then aligns the threaded hole 722 inside the installation block 721 with the threaded hole 722 inside the rear plate 3, and then the operator screws the screw 723 into the threaded hole 722, thereby realizing the installation of the electric cylinder 71 and ensuring the necessary conditions for the use of the electric cylinder 71.

[0031] refer to Figure 3The top and bottom of the movable splint 6 are both provided with sliding grooves 9, and the movable splint 6 is slidably connected to the surface of the guide rod 4 through the sliding grooves 9.

[0032] As a technical optimization solution of the utility model, by setting the sliding groove 9, the movable splint 6 is slidably installed on the surface of the guide rod 4 through the sliding groove 9, so that the movable splint 6 can slide conveniently, thereby improving the convenience of moving the movable splint 6.

[0033] refer to Figure 2 and Figure 4 A protection box 10 is fixedly connected to the back of the rear plate 3 , and the controller 82 is located inside the protection box 10 .

[0034] As a technical optimization solution of the utility model, a protection box 10 is provided so that the protection box 10 and the rear plate 3 are fixedly installed, and then the protection box 10 protects the controller 82 to prevent the controller 82 from being accidentally touched and hit by external forces.

[0035] refer to Figure 2 The back of the protection box 10 is movably connected to a switch door 11 through a hinge, and a handle 12 is fixedly connected to the left side of the back of the switch door 11.

[0036] As a technical optimization solution of the utility model, by setting the switch door 11 and the handle 12, when the operator needs to use the controller 82, the operator pulls the handle 12 to drive the switch door 11 to flip through the hinge, and then opens the protective box 10, so that the operator can conveniently use the controller 82.

[0037] The working principle and use process of the utility model are as follows: when the operator needs to install the plate 2, the front plate 1 is fixedly installed with the rear plate 3 through the guide rod 4, so that the front plate 1, the guide rod 4 and the rear plate 3 form an integral frame, and then the operator places multiple plates 2 on the surface of the guide rod 4 through the guide groove 5, and then the operator starts the electric cylinder 71, so that the electric cylinder 71 drives the movable clamping plate 6 to move toward the plate 2, so that the movable clamping plate 6 presses against the plate 2, and when pressing, the pressure sensor 81 transmits the pressure value to the controller 8 through the wire. 2, when the set threshold is reached, the controller 82 turns off the electric cylinder 71 to prevent the electric cylinder 71 from continuously applying pressure to damage the plate 2, thereby completing the installation, thereby improving the convenience of the operator in fixing the plate 2. At the same time, the electric cylinders 71 arranged at the four corners can well ensure that the force at each position of the movable clamping plate 6 is uniform. When the operator needs to remove the plate 2, the operator controls the output end of the electric cylinder 71 to retract, so that the movable clamping plate 6 no longer presses against the plate 2, so that the operator can conveniently remove the plate 2.

[0038] To sum up: this kind of plate heat exchanger fixing structure, by setting the guide rod 4, the guide groove 5, the movable clamp 6, the moving component 7 and the limit component 8, makes the plate 2 slide and be installed on the surface of the guide rod 4 through the guide groove 5, and then makes the moving component 7 drive the movable clamp 6 to press against the plate 2, so as to complete the fixation. When it is necessary to remove the plate 2, the moving component 7 drives the movable clamp 6 away from the plate 2, so that the plate 2 can be taken out, thereby improving the convenience of the operator to install and remove the plate 2, and solving the problem of needing to disassemble and clean the heat exchange plate during actual use. Since the existing plate fixing method is usually fixed together by bolts through a clamp or a pressure plate to form a frame structure, in order to ensure the stability of the plate, multiple bolts are often used for fixing. Then, when disassembling, it causes the operator to disassemble cumbersomely and reduce the work efficiency.
