[0002] Plate heat exchangers are efficient, compact, and widely used heat exchange devices. They are mainly composed of a series of corrugated metal plates stacked together, forming thin rectangular channels through which heat is exchanged.

[0003] Plate heat exchangers achieve heat exchange through the flow of two media. When water is used, due to the nature of the medium itself, the water may contain a lot of impurities that remain on the plates of the plate heat exchanger. These impurities can prevent the medium from flowing smoothly between the plates, thus affecting the heat exchange effect and consequently the stability of the plate heat exchanger during use.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 The present invention provides the following technical solution: a plate heat exchanger with good stability, comprising a heat exchanger body 1, a heat inlet 2 fixedly connected to one side surface of the heat exchanger body 1, a heat outlet 3 fixedly connected to one side surface of the heat exchanger body 1 at the lower end of the heat inlet 2, a cold inlet 4 fixedly connected to one side surface of the heat exchanger body 1 at one end of the heat outlet 3, a cold outlet 5 fixedly connected to one side surface of the heat exchanger body 1 at the top of the cold inlet 4, a connecting block 6 fixedly connected to the other side surface of both the heat inlet 2 and the cold inlet 4, a flow pipe 7 connected to the other side surface of the connecting block 6, and a placement groove 8 opened on the top surface of the connecting block 6, a filter screen 9 slidably placed on the inner surface of the placement groove 8, a slot 12 opened on one side surface at the top of the filter screen 9, one end of a movable insert rod 13 connected to the inner surface of the slot 12, and support feet 17 connected to the bottom surface of the four corners of the heat exchanger body 1.

[0018] Preferably, a sealing ring 10 is connected around the outer surface of the filter screen 9 at the top of the slot 12. One end of the sealing ring 10 extends into the slot 11 opened on the inner surface of the placement slot 8. The sealing ring 10 and the connecting block 6 form an engaging structure through the slot 11.

[0019] In practical use, the filter screen 9 can be customized to the required shape and size. When the filter screen 9 is slid into the placement groove 8, the filter screen 9 will move to the slot 11 with the sealing ring 10. The sealing ring 10 will be elastically engaged in the slot 11, thereby increasing the sealing between the filter screen 9 and the connecting block 6 and preventing the medium from escaping from the placement groove 8. The sealing ring 10 is made of rubber.

[0020] Preferably, the other end of the movable insert rod 13 is connected to a protrusion 14, the protrusion 14 is symmetrically embedded on one side surface of the connecting block 6, and the protrusion 14 is provided with a spring 15 that is penetrated by the movable insert rod 13. The movable insert rod 13 and the protrusion 14 form an elastic structure through the spring 15.

[0021] In actual use, when the movable rod 13 slides on the protrusion 14, the movable rod 13 will elastically extend and retract on the protrusion 14 through the spring 15. The top of the end of the movable rod 13 that extends into the placement groove 8 has a downwardly inclined slant.

[0022] Preferably, a pull rod 16 is provided on one side of the connecting block 6, and both ends of the pull rod 16 facing the connecting block 6 are connected to the movable insert rod 13.

[0023] In actual use, pulling the lever 16 will cause the lever 16 to slide on the protrusion 14 by pulling the two movable inserts 13.

[0024] Preferably, a mounting plate 18 is connected to the inner surface of the support foot 17, and an electric push rod 19 is connected to the bottom surface of the mounting plate 18. The movable end of the electric push rod 19 passes through the mounting plate 18 and is connected to the movable frame 20. The other end of the movable frame 20 passes through the mounting plate 18 and is connected to the pulley 21.

[0025] In practical use, the electric push rod 19 is activated, causing the movable end of the electric push rod 19 to drive the movable frame 20 to slide on the mounting plate 18. In this way, the pulley 21 at the bottom of the movable frame 20 can contact the ground and support the heat exchanger body 1. At this time, the heat exchanger body 1 can be easily moved by the pulley 21. When the heat exchanger body 1 is moved to the designated position, the electric push rod 19 can be activated again, causing the movable end of the electric push rod 19 to drive the pulley 21 at the bottom of the movable frame 20 to move, so that the support foot 17 contacts the ground again, thereby ensuring the stability of the heat exchanger body 1 when it is placed and used.

[0026] Preferably, the electric push rod 19 is electrically connected to an external power source via a control switch, and the movable frame 20 and the mounting plate 18 form a sliding connection.

[0027] In actual use, the electric push rod 19 can be controlled by a switch, and the movable frame 20 can slide on the mounting plate 18, thereby driving the pulley 21 at the bottom of the movable frame 20 to move.

[0028] Working principle: When using this stable plate heat exchanger, install the heat exchanger body 1 at the designated position. Then, slide the filter screen 9 into the placement groove 8 on the connecting block 6 at the hot inlet 2 and cold inlet 4 respectively. As the filter screen 9 slides in the placement groove 8, it presses against the movable rod 13, causing the movable rod 13 to press against the spring 15 in the protrusion 14. When the filter screen 9 is fully placed in the placement groove 8, the spring 15 will elastically push the movable rod 13 to move, allowing one end of the movable rod 13 to insert into the slot 12 on the filter screen 9. In this way, the position of the filter screen 9 will be fixed on the connecting block 6. Then, connect the flow pipe 7 on the connecting block 6 to the medium pipeline. When the medium flows into the hot inlet 2 and cold inlet 4, the filter screen 9 will filter the flowing medium, thereby reducing the impurity content in the flowing medium and preventing contamination. Excessive sediment can easily affect the flow of the medium. To ensure the heat exchange effect of the plate heat exchanger and enhance its stability during use, the pull rod 16 can be pulled to move the two movable insert rods 13 simultaneously, allowing one end of the movable insert rod 13 to separate from the slot 12. This allows the filter screen 9 to be pulled out from the placement slot 8, enabling operators to maintain and replace the filter screen 9 and ensure its effectiveness. Secondly, when the heat exchanger body 1 needs to be moved, the electric push rod 19 can be activated, allowing the movable end of the electric push rod 19 to drive the movable frame 20 to slide on the mounting plate 18. This allows the pulley 21 at the bottom of the movable frame 20 to contact the ground and support the heat exchanger body 1. The pulley 21 then facilitates the movement of the heat exchanger body 1, preventing operators from having to manually move it, thus making the movement of the plate heat exchanger more convenient.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
