Description

Technical Field

[0001] This utility model belongs to the technical field of plate heat exchangers, specifically a plate heat exchanger that is easy to clean. Background Technology

[0002] A plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal plates with a specific corrugated shape. Thin rectangular channels are formed between the plates, through which heat exchange occurs. Plate heat exchangers are ideal devices for liquid-liquid and liquid-vapor heat exchange, featuring high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life.

[0003] Existing plate heat exchangers require the heat exchange plates to be disassembled during cleaning, but the heat exchange plates are generally installed using multiple sets of fixing screws, making disassembly quite troublesome. Summary of the Invention

[0004] The purpose of this invention is to provide a plate heat exchanger that is easy to clean, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a plate heat exchanger that is easy to clean, including a bracket, a screw connected to the outer wall of the bracket by a bearing, a handwheel fixedly connected to one end of the screw, a threaded slider threadedly connected to the outer wall of the screw, a clamping frame fixedly connected to the outer wall of the threaded slider, a mounting plate fixedly connected to the outer wall of the clamping frame, a limiting rod fixedly connected to the inner wall of the mounting plate and the inner wall of the bracket passing through the inner wall of the mounting plate, a heat exchange plate tightly fitted to the outer wall of the mounting plate and fitted with the outer wall of the limiting rod, a connecting pipe provided on one side of the heat exchange plate, and a cooling pipe provided on one side of the connecting pipe.

[0006] Based on the above structure, when the handwheel is rotated, the screw drives the threaded slider to move. The movement of the threaded slider causes the mounting plate on the outer wall of the clamping frame to slide along the outer wall of the limiting rod. The sliding of the mounting plate causes the heat exchange plate to fit tightly, realizing the quick installation of the heat exchange plate and facilitating the cleaning of the heat exchange plate. At the same time, by setting the limiting rod, misalignment of the heat exchange plate is prevented during installation.

[0007] Preferably, the clamping frame is C-shaped, and the mounting plate forms a sliding structure with the limiting rod through a screw and a threaded slider. In this embodiment, when the handwheel is rotated, the screw drives the threaded slider to move, and the movement of the threaded slider causes the mounting plate on the outer wall of the clamping frame to slide along the outer wall of the limiting rod. By setting the C-shaped clamping frame, the mounting plate is prevented from shifting during sliding.

[0008] Preferably, two sets of limiting rods are provided, and the two sets of limiting rods are parallel. In this embodiment, by providing two sets of limiting rods, it is beneficial to improve the stability of the sliding of the mounting plate.

[0009] Preferably, the cross-section of the limit rod is circular, and a positioning groove is provided at the connecting position of the heat exchange plate and the limit rod. In this embodiment, by providing the limit rod with a circular cross-section, dislocation of the heat exchange plate during installation is avoided.

A backflushing hole is opened on one side of the reversing valve rod, and a connecting port is fixedly connected to the outer wall of the backflushing frame. In this embodiment, the electric push rod works to drive the telescopic rod to slide vertically, and the sliding of the telescopic rod drives the reversing valve rod to slide along the inner wall of the backflushing frame, so that the connecting port is communicated with the water outlet of the connecting pipe through the backflushing hole, thereby realizing backflushing of the heat exchange plate, discharging dirt attached to the outer wall of the heat exchange plate through the connecting pipe, and realizing rapid cleaning of the heat exchange plate.

[0011] Preferably, the shape of the reversing valve rod is king-shaped. In this embodiment, by arranging the king-shaped reversing valve rod, it is convenient for the electric push rod to work to drive the telescopic rod to slide vertically, and the sliding of the telescopic rod drives the reversing valve rod to slide along the inner wall of the backflushing frame, so that the connecting port is communicated with the water outlet of the connecting pipe through the backflushing hole, and backflushing of the heat exchange plate is realized.

[0012] Preferably, both the connecting pipes and the connecting ports are provided in two groups. In this embodiment, by providing two groups of connecting pipes and connecting ports, backflushing of the heat exchange plate is facilitated.

[0019] This utility model discloses a plate heat exchanger that is easy to clean, including a support 1. A screw 2 is connected to the outer wall of the support 1 by a bearing.

A connecting pipe 9 is provided on one side of the heat exchange plate 8, and a cooling pipe 10 is provided on one side of the connecting pipe 9.

[0020] Based on the above structure, when the handwheel 3 rotates, the screw 2 drives the threaded slider 4 to move, thereby causing the mounting plate 6 on the outer wall of the clamping frame 5 to slide along the outer wall of the limiting rod 7, which in turn causes the heat exchange plate 8 to fit tightly, realizing the quick installation of the heat exchange plate 8 and facilitating the cleaning of the heat exchange plate 8; at the same time, by setting the limiting rod 7, misalignment of the heat exchange plate 8 during installation is prevented.

[0021] In one embodiment, the clamping frame 5 is C-shaped, and the mounting plate 6 forms a sliding structure with the limiting rod 7 through the screw 2 and the threaded slider 4.

[0022] In this embodiment, when the handwheel 3 is rotated, the threaded slider 4 is driven to move by the screw 2, and the movement of the threaded slider 4 drives the mounting plate 6 on the outer wall of the pressing frame 5 to slide along the outer wall of the limit rod 7. By providing the C-shaped pressing frame 5, the mounting plate 6 is prevented from shifting during sliding.

[0023] In one embodiment, two sets of limit rods 7 are provided, and the two sets of limit rods 7 are parallel to each other.

[0024] In this embodiment, providing two sets of limit rods 7 is beneficial to improving the sliding stability of the mounting plate 6.

[0025] In one embodiment, the cross-section of the limit rod 7 is circular, and a positioning groove is provided at the connecting position between the heat exchange plate 8 and the limit rod 7.

[0026] In this embodiment, by providing the limit rod 7 with a circular cross-section, dislocation of the heat exchange plate 8 during installation is avoided.

[0027] In one embodiment, one end of the connecting pipe 9 is fixedly connected with a backflushing frame 11, the top end of the backflushing frame 11 is fixedly connected with an electric push rod 12, the output end of the electric push rod 12 is fixedly connected with a telescopic rod 13, one end of the telescopic rod 13 is fixedly connected with a reversing valve rod 14 which is in sealed connection with the inner wall of the backflushing frame 11, a backflushing hole 15 is opened on one side of the reversing valve rod 14, and a connecting port 16 is fixedly connected to the outer wall of the backflushing frame 11.

[0028] In this embodiment, when the electric push rod 12 operates, it drives the telescopic rod 13 to slide vertically, thereby driving the reversing valve rod 14 to slide along the inner wall of the backflushing frame 11, so that the connecting port 16 communicates with the water outlet of the connecting pipe 9 through the backflushing hole 15, realizing backflushing of the heat exchange plate 8, discharging dirt attached to the outer wall of the heat exchange plate 8 through the connecting pipe 9, and realizing rapid cleaning of the heat exchange plate 8.

[0029] In one embodiment, the outer shape of the reversing valve rod 14 is king-shaped.

[0035] When the heat exchange plate 8 needs to be disassembled or assembled, turn the handwheel 3. When the handwheel 3 rotates, the screw 2 drives the threaded slider 4 to move, thereby causing the mounting plate 6 on the outer wall of the clamping frame 5 to slide along the outer wall of the limiting rod 7, which in turn causes the heat exchange plate 8 to fit tightly, realizing the quick installation of the heat exchange plate 8 and facilitating the cleaning of the heat exchange plate 8; at the same time, by setting the limiting rod 7, the misalignment of the heat exchange plate 8 during installation is prevented.
