[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to a plate heat exchanger that is easy to clean. Background Technology
[0002] A plate heat exchanger is a device used to transfer heat, typically for heating, cooling, or evaporation. It consists of multiple stacked plates, each with a series of fluid channels that allow heat to be transferred from one fluid to another through the plate walls.

This device pulls out individual plates for cleaning, which is not convenient for pulling out and retracting all plates at the same time. This individual operation method is not convenient and fast enough, and reduces the cleaning efficiency of the plates. Utility Model Content
[0004] The purpose of this invention is to provide a plate heat exchanger that is easy to clean, with the advantage of being able to pull out several plates simultaneously for cleaning.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plate heat exchanger that is easy to clean, including a fixed plate, a limiting plate provided on one side of the fixed plate, a plate provided between the fixed plate and the limiting plate, the number of the plate being several, a connecting shaft fixedly connected to both sides of the plate, a connecting rod rotatably connected to one end of the connecting shaft, a fixing block fixedly connected to one end of one of the connecting shafts, and one side of the fixing block being fixedly connected to one side of the limiting plate.
[0006] The above technical solution facilitates the pulling out and separating of all the plates together, which is convenient for subsequent cleaning and improves the cleaning efficiency of the plates.
[0007] The present invention is further configured such that the two ends of the connecting rod are respectively disposed on different plates.
[0008] The above technical solution facilitates the movement of the plates.
[0009] The present invention is further configured such that the fixing plate includes a screw, a nut and a support leg, and the inner walls of both the fixing plate and the limiting plate are provided with screws, and the outer side of the screw is threaded with a nut.
[0010] The above technical solution facilitates the clamping force between the fixing plate and the limiting plate to fix the plate.
[0011] The present invention is further configured such that the bottom of both the fixing plate and the limiting plate are fixedly connected to a support leg, and the inner wall of the support leg is provided with a positioning hole.
[0012] The above technical solution facilitates the fixing of the fixing plate and the limiting plate.
[0013] The present invention is further configured such that the number of screws is six, and the six screws are arranged at equal intervals.
[0014] The above technical solution improves the fixation effect on the plates.
[0015] The present invention is further configured such that a guide rod is fixedly connected to one side of the fixing plate, and one end of the guide rod passes through one side of the limiting plate.
[0016] The above technical solution is adopted to ensure stable movement of the plates.
[0017] The present invention is further configured such that there are two guide rods, and the two guide rods are arranged symmetrically.
[0018] By adopting the above technical solution, when the screw is removed by loosening the nut, the fixing plate and the limiting plate can be kept vertical.
[0019] The present invention is further configured such that the inner walls of the limiting plate and the plate are provided with guide grooves for use with the guide rod.
[0020] The above technical solution can prevent plate misalignment.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1: By moving the limiting plate, the fixed block drives one of the plates to move. When the first plate moves, it drives the connecting rod to move. When the connecting rod moves through the connecting shaft, it drives another plate to move. This process can be repeated to separate all the plates together, making subsequent cleaning easier and improving the cleaning efficiency of the plates.
[0023] 2: By using the guide rod and guide groove together, the plate can be kept stable during movement and the removed plate can be kept vertical without deviation, which facilitates the cleaning work. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] Example 1:
[0030] refer to Figure 1 , Figure 2 and Figure 3 A plate heat exchanger that is easy to clean includes a fixed plate 1, a limiting plate 2 is provided on one side of the fixed plate 1, and a plate 3 is provided between the fixed plate 1 and the limiting plate 2. There are several plates 3. A connecting shaft 4 is fixedly connected to both sides of the plate 3. A connecting rod 5 is rotatably connected to one end of the connecting shaft 4. A fixing block 6 is fixedly connected to one end of one of the connecting shafts 4. One side of the fixing block 6 is fixedly connected to one side of the limiting plate 2.
[0031] The two ends of the connecting rod 5 are respectively set on different plates 3.
[0032] The fixing plate 1 includes a screw 101, a nut 102 and a support leg 103. The inner walls of both the fixing plate 1 and the limiting plate 2 are provided with screws 101, and the outer side of the screw 101 is threaded with a nut 102.
