DETAILED DESCRIPTION

[0023] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0024] As Figures 1-4As shown, the embodiment provides a plate heat exchanger, which comprises a stand 1, a fixed compression plate 2, two bearing guide rods 3, a movable compression plate 4, a heat transfer core 5, a plurality of clamping bolts 6 and at least one bottom support 7. The stand 1 is vertically arranged behind the fixed compression plate 2 and spaced apart from the fixed compression plate 2. The fixed compression plate 2 is arranged in a length direction along a vertical direction, in a width direction along a left-right direction and in a thickness direction along a front-rear direction. The two bearing guide rods 3 are arranged in a front-rear direction, one above the other, and spaced apart from each other; the upper bearing guide rod 3 is connected at both ends thereof to the stand 1 and the top (including but not limited to the top end, for example, the side close to the top end) of the fixed compression plate 2, respectively; and the lower bearing guide rod 3 is connected at both ends thereof to the stand 1 and the bottom (including but not limited to the bottom end) of the fixed compression plate 2, respectively. The stand 1, the fixed compression plate 2 and the two bearing guide rods 3 form a frame structure similar to a rectangle, wherein the stand 1 and the fixed compression plate 2 are fixed to the ground by anchor bolts or the like. The movable compression plate 4 is arranged in a length direction along a vertical direction, in a width direction along a left-right direction and in a thickness direction along a front-rear direction, and is movably arranged between the stand 1 and the fixed compression plate 2, i.e. in the frame structure. The heat transfer core 5 is also arranged in the frame structure and is fixed between the fixed compression plate 2 and the movable compression plate 4 by the clamping bolts 6 (this is a prior art). The bottom support 7 is arranged at the bottom of the movable compression plate 4.

[0025] The bottom support 7 arranged at the bottom of the movable compression plate 4 reduces the strength requirement of the bearing guide rod 3, saves cost, and effectively avoids the problem of deformation of the upper bearing guide rod 3 caused by the weight of the movable compression plate 4 and the heat transfer core 5, thereby avoiding the problem of medium leakage possibly caused by the deformation of the bearing guide rod 3.

[0026] In the embodiment, the bottom support 7 adopts a rolling structure, which comprises two bottom mounting plates 71, a support shaft 72 and a support wheel 73. The bottom mounting plate 71 comprises two plates perpendicular to each other (one is called a fixed plate and the other is called a shaft passing plate) and is bent from one plate; the fixed plates of the two bottom mounting plates 71 are connected to the movable compression plate 4, respectively; and the shaft passing plates of the two bottom mounting plates 71 are arranged in parallel and spaced apart. The support shaft 72 is fixed transversely between the two shaft passing plates; the support shaft 72 can be replaced by a bolt. The support wheel 73 is rotatably mounted on the support shaft 72, and the wheel surface of the support wheel 73 can protrude from the bottom end of the movable compression plate 4 and the bottom mounting plate 71; in this way, when the support wheel 73 is in contact with the ground, the movable compression plate 4 or the bottom mounting plate 71 is not in contact with the ground, thereby avoiding scratching and friction between the movable compression plate 4 or the bottom mounting plate 71 and the ground, which causes the movable compression plate 4 to be difficult to move.

[0027] The bottom supports 7 can be provided in plurality, and the plurality of bottom supports 7 are distributed at intervals on the bottom edge of the movable compression plate 4, and can bear greater weight. In the embodiment, two bottom supports 7 are provided, and the two bottom supports 7 are respectively arranged at the two corners of the bottom of the movable compression plate 4.

[0028] Generally, the plate heat exchanger further comprises a top suspension 8, which is arranged at the top of the movable compression plate 4, and the movable compression plate 4 is hung below the upper bearing guide rod 3 through the top suspension 8. In the prior art, when the movable compression plate 4 moves along the bearing guide rod 3, the top suspension 8 and the upper bearing guide rail are in sliding friction, and the friction is relatively large, which is not conducive to moving the movable compression plate 4 when the plate pieces are increased or decreased.

[0029] In the embodiment, the top suspension 8 adopts a rolling structure, which comprises two top mounting plates 81, a suspension shaft 82 and a suspension roller 83. The top mounting plate 81 comprises two plates (one is called a fixed plate, and the other is called a shaft passing plate) perpendicular to each other, which are bent from one plate; the fixed plates of the two top mounting plates 81 are connected with the movable compression plate 4, and the shaft passing plates of the two top mounting plates 81 are arranged in parallel and are arranged on the left and right sides of the upper bearing guide rod 3. The shaft passing plate does not contact the bearing guide rod 3. The suspension shaft 82 is transversely fixed between the two top mounting plates 81, and the suspension shaft 82 is located above the upper bearing guide rod 3, and the suspension shaft 82 can be replaced by a bolt. The suspension roller 83 is rotatably mounted on the suspension shaft 82, and the roller surface of the suspension roller 83 abuts against the upper surface of the upper bearing guide rod 3. In this way, when the movable compression plate 4 moves along the bearing guide rod 3, not only can it move by rolling through the bottom support 7, but also can move by rolling through the top suspension 8, thereby reducing the resistance when moving. Preferably, the top surface of the upper bearing guide rod 3 is an arc surface concave downward, and the roller surface of the suspension roller 83 is an arc surface convex outward, which are matched with each other, so as to ensure the centering performance of the movable compression plate 4 when moving, and can effectively avoid the sliding friction resistance generated by the contact between the shaft passing plate and the bearing guide rod 3.

[0030] Generally, one top suspension 8 is provided. In the embodiment, two top suspensions 8 are provided, and the two top suspensions 8 are arranged on the two sides in the thickness direction of the movable compression plate 4, so that the movable compression plate 4 can be more stable.
