Description

Technical Field

[0001] The utility model belongs to the technical field of chemical machinery and relates to a plate heat exchanger plate transportation and cleaning vehicle. Background Art

[0002] A plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with corrugated shapes. Thin rectangular channels are formed between the plates of the plate heat exchanger, and heat exchange is carried out through the plates. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small floor area, convenient installation and cleaning, wide application, long service life, etc.

[0003] The plate heat exchanger used in the polyester plant is produced by Alfa Laval. The inspection and cleaning of the plate heat exchanger is a positive maintenance method. Appropriate measures need to be taken to clean the plates to keep the heat transfer surface clean at all times to maintain the heat transfer effect and prevent the corrosion of the device.

[0004] Generally speaking, cleaning the outer surface of the heat exchanger during operation has little effect, while cleaning the plates is very effective. In order to remove the accumulated dirt, it is very necessary to regularly open the device to take out the plates and clean them.

[0005] At present, for example, CN205059675U provides a flatbed truck for transporting plates. Those skilled in the art usually disassemble the plates, place them horizontally on the flatbed truck, and then transport them to the designated position and place the plates on the ground one by one to clean the front and back sides. When cleaning, they use running water to scrub and then rinse with a high-pressure hose. However, this method has obvious disadvantages. The operator is prone to damage the plates during operation and it is time-consuming and laborious with low efficiency.

[0006] Therefore, it is of great significance to study a plate heat exchanger plate transportation and cleaning vehicle to more conveniently clean the plates of the plate heat exchanger. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the problems existing in the prior art and provide a plate heat exchanger plate transportation and cleaning vehicle.

[0009] A plate heat exchanger plate transportation and cleaning vehicle is used for transporting and assisting in cleaning the plates of the plate heat exchanger; the plates of the plate heat exchanger are rectangular plates; along the direction perpendicular to the thickness of the rectangular plate, dovetail grooves are respectively arranged on two opposite side surfaces of the rectangular plate; the length of the dovetail groove is the same as the thickness of the rectangular plate, and the length direction of the dovetail groove is parallel to the thickness direction of the rectangular plate. The plate heat exchanger plate transportation and cleaning vehicle includes a bottom plate, guide rods, wheels, support rods, vertical rods, a moving mechanism and a horizontal rod;

[0010] The vertical rod is located above the bottom plate and fixedly connected to the bottom plate;

[0011] The support rod is horizontally placed and fixedly connected to the vertical rod;

[0012] The moving mechanism includes a bolt and a nut; the bolt passes through the support rod from bottom to top and is cooperatively connected with the nut; the head of the bolt (bolt head) is fixedly connected to the horizontal rod; by rotating the nut, the distance between the bolt head and the support rod can be adjusted, thereby driving the horizontal rod to move up and down;

[0014] The relationship among D, w, and d satisfies: w < d < D, that is, after the horizontal rod passes through the dovetail groove of the rectangular plate, the rectangular plate does not fall off the horizontal rod;

[0015] The guide rod is horizontally placed and fixed on the upper surface of the bottom plate; the guide rod is used to cooperate with the dovetail groove on the rectangular plate to guide the rectangular plate;

[0017] When used for transporting the plates of the plate heat exchanger, one dovetail groove of multiple plates of the plate heat exchanger is sequentially passed through by the horizontal rod and hung on the horizontal rod, multiple plates of the plate heat exchanger are mutually attached, then the moving mechanism is started, and multiple plates of the plate heat exchanger move downward. The other dovetail groove of multiple plates of the plate heat exchanger cooperates with the guide rod for guiding and is subjected to the downward pressure of the horizontal rod, so as to play a role in fixing;

[0018] When used for cleaning the plates of the plate heat exchanger, the moving mechanism is started, multiple plates of the plate heat exchanger move upward, so that multiple plates of the plate heat exchanger are suspended in the air, and then multiple plates of the plate heat exchanger are toggled to slide on the horizontal rod, so that the plates of the plate heat exchanger are separated from each other to facilitate flushing the plane where the plates of the plate heat exchanger are attached.

[0026] The plate heat exchanger plate is provided with a through hole penetrating the plate heat exchanger plate; the diameter of the through hole is greater than the minimum circle diameter capable of accommodating the cross-section of rod II;

[0027] When transporting small-sized plate heat exchanger plates, remove the moving mechanism on the support rod, adjust the height of the support rod, pass rod II in the support rod through the through hole, and hang the small-sized plate heat exchanger plates, then the transportation of the plate heat exchanger plates can be realized. Then when cleaning the plate heat exchanger plates, let them slide on the horizontal rod, so that the plate heat exchanger plates are separated from each other, so as to facilitate flushing the flat surfaces where the plate heat exchanger plates are attached to each other.

[0028] Beneficial effects:

[0029] (1) Using the device of the present utility model can avoid damaging the plates and rubber gaskets caused by using a flatbed truck to transport the plates. At the same time, it improves the cleaning work efficiency, saves time costs, and improves the cleaning cleanliness; at the same time, it is provided with a detachable suspension bracket composed of a moving mechanism and a horizontal rod, which can be applied to the suspension, transportation, and cleaning of plates of different specifications;
