Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger plate cleaning, in particular to a heat exchanger plate cleaning device. Background Art

[0002] Heat exchanger plates are the core components of plate heat exchangers used to isolate media and perform heat exchange. Their main function is to facilitate heat transfer between two fluids of different temperatures.

[0003] Common heat exchanger plates are usually made of stainless steel, titanium, high-nickel alloy and other materials. Each plate consists of two parts: a metal plate and a sealing gasket. The metal plate is a thin metal plate with pressed corrugations, sealing grooves and corner holes. These corrugations not only enhance the heat transfer effect, but also increase the rigidity and pressure-bearing capacity of the plate.

[0004] During the daily use of the heat exchanger, varying degrees of scale or sediment may form on the surface of the plate. These scales will reduce the heat transfer efficiency and increase the flow resistance, so the heat exchanger plates need to be cleaned.

[0005] When cleaning the heat exchanger plates, you first need to use a high-pressure water gun to flush the surface of the heat exchanger plates so that the dirt and sediment on the surface that are easy to clean can be washed away by the water gun. Then, you need to place the heat exchanger plates in a liquid nitrogen tank to make the glue and gasket fall off the plates. Finally, depending on the type and degree of dirt, the plates are immersed in an alkaline or acid cleaning tank for chemical cleaning.

[0006] When washing the heat exchanger plates with a high-pressure water gun, in order to ensure that the surface of the plates is washed clean and to ensure the cleaning effect, the technical workers need to hold the water gun and carefully wash the plates one by one. This process requires the workers to clean both the front and back of each plate, which will undoubtedly prolong the cleaning time and reduce the cleaning efficiency. Summary of the invention

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a heat exchanger plate cleaning device, which can help workers clean two heat exchanger plates at one time without the need for workers to turn over the plates.

[0033] The installation assembly 100 includes a storage box 101, a splash shield 102 connected to the top of the storage box 101, and a rotating shaft 103 disposed on the top of the storage box 101, wherein a corresponding motor and related electronic components are also installed in the storage box 101, and a drainage device can also be installed in the storage box 101 according to needs;

[0034] It should be noted that the output end of the motor is connected to the rotating shaft 103 , and the splash shield 102 can be made of transparent glass to facilitate workers to observe the heat exchanger plates inside the splash shield 102 .

[0035] The power assembly 200 is connected to the top of the rotating shaft 103, and includes a connecting member 201 and a pushing member 202. The bottom of the connecting member 201 is connected to the top of the rotating shaft 103. When the rotating shaft 103 rotates, the connecting member 201 is driven to rotate, so that the pushing member 202 can be driven to rotate. The heat exchanger plate is fixed on the pushing member 202. Figure 3 As shown, two pushing members 202 in opposite directions are respectively arranged on both sides of the connecting member 201, and the different pushing members 202 on both sides are respectively connected to a heat exchanger plate, so that when the connecting member 201 rotates, it will drive the two plates to rotate, so that when the workers use a high-pressure water gun to wash, the two plates can be washed in turn, and when the rotating shaft 103 rotates in the opposite direction, the two plates will rotate under the action of wind force and inertia, and then the two plates are turned over, so that the workers can quickly wash the back of the plates.

[0036] Example 2

[0037] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, but differs in that it further explains how the connecting member 201 and the pushing member 202 achieve the effect in embodiment 1.

[0038] The connecting member 201 includes a rotating rod 201a, a connecting plate 201b arranged at the bottom of the rotating rod 201a, and an assembly piece 201c connected to the outer wall of the rotating rod 201a, wherein the rotating rod 201a and the assembly piece 201c are integrated, and rectangular connecting pieces are arranged on both sides of the assembly piece 201c, and through holes are respectively opened on both sides of the connecting piece for connecting bolts.

[0039] A flange is provided on the top of the rotating shaft 103, the connecting plate 201b is connected to the flange, one side of the fixing rod 202a is connected to the assembly plate 201c by bolts, the rotating rod 201a and the fixing rod 202a are perpendicular to each other, wherein the bottom of the rotating shaft 103 is connected to a motor.

[0040] The pushing member 202 includes a fixed rod 202a, a connecting groove 202b provided on one side of the fixed rod 202a, a rotating clamp 202c rotatably connected to the inner wall of the connecting groove 202b, and a clamping block 202g provided on one side of the fixed rod 202a, one side of the rotating clamp 202c is threadedly connected to a threaded rod 202d, one side of the threaded rod 202d is provided with a clamping plate 202e, one side of the clamping plate 202e is in contact with one side of the rotating clamp 202c, one side of the threaded rod 202d is provided with a handle, and the rotating clamp 202c is perpendicular to the rotating rod 201a, wherein the fixed rod 202a is a long rod symmetrical on both sides, and when it is installed on the rotating rod 201a, the length of one side is greater than the length of the other side, as shown here Figure 3 As shown, a plurality of rotating rods 201a are arranged on the rotating rod 201a, and the rotating rods 201a on the same side are used to connect the same plate;

[0041] It should be noted that when the plate needs to be fixed, one side of the plate is placed in the middle of the rotating clamp 202c, and then the clamping plate 202e can be clamped by rotating the threaded rod 202d.

[0042] A friction plate 202f is connected to one side of the rotating clamp 202c. The friction plate 202f is rectangular in shape. The friction plate 202f and the rotating clamp 202c are perpendicular to each other. The engaging block 202g is arranged adjacent to the connecting groove 202b. A engaging groove 202h is arranged on one side of the engaging block 202g. A rubber block 202i is installed on the inner wall of the engaging groove 202h. The width of the engaging groove 202h is greater than the width of the friction plate 202f. The outer wall of the friction plate 202f is in contact with the rubber block 202i. When the rotating rod 201a rotates, the rotating clamp 202c is driven to rotate under the action of inertia. At this time, the friction plate 202f will rotate into the connecting groove 202b. At this time, the rubber block 202i will be in contact with the friction plate 202f. At this time, under the action of friction, the rotating clamp 202c will not rotate easily. When the rotation is continuously performed in the same direction, the rotating clamp 202c will be kept in the same position, thereby keeping the plate rotating in the same position. When the rotating rod 201a rotates in the opposite direction, the rotating clamp 202c will rotate in the opposite direction under the action of inertia and the air friction force on the plate. At this time, the friction plate 202f will be disengaged from the engaging groove 202h. When the rotating clamp 202c is rotated to the other side, the plate will be turned over. At this time, the friction plate 202f on the other side of the rotating clamp 202c will enter the engaging block 202g on the other side of the fixed rod 202a. At this time, the plate has completed the turning over and can also be kept in this position for continuous rotation. In this way, two different plates can be cleaned at the same time, which is convenient for workers to quickly rinse both sides of the plate and improve the cleaning efficiency of the heat exchanger plate.

[0043] Example 3

[0044] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, is based on the previous embodiment, and the difference is that the friction force can be increased by replacing the material of the friction plate 202f.

[0045] A friction plate 202f is connected to one side of the rotating clamp 202c. The friction plate 202f has a rectangular shape. The friction plate 202f and the rotating clamp 202c are perpendicular to each other. The width of the engaging groove 202h is greater than the width of the friction plate 202f. The outer wall of the friction plate 202f is in contact with the rubber block 202i. The friction plate 202f mentioned above is made of plastic material, and silicon carbide ceramic material can be used here to increase the friction coefficient between the friction plate 202f and the rubber block 202i.
