Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a plate of a plate heat exchanger. Background Art

[0002] The plate heat exchanger is a highly efficient heat exchange device, which is composed of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between these plates, and heat is exchanged through the plates.

[0003] A Chinese patent discloses a plate heat exchanger plate (authorization announcement number CN201436546U). The support point of the patented technology occupies a smaller area of ​​the diversion zone, and the water flow can flow from the crenel below the support point to the diversion zone. The crenel reduces the resistance of the support point to the water flow, which effectively solves the problem of water flow blocking the diversion zone.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during the installation process of existing plate heat exchanger plates, most of them are compressed and fixed by bolts, which makes the entire plate bundle an indivisible whole. Once one or several plates in the plate bundle are damaged, the entire plate bundle needs to be replaced, which not only increases the maintenance cost, but also causes a waste of resources. Utility Model Content

[0005] The technical problem to be solved by the utility model is that: in the prior art, there is a disadvantage that most of the plates are fixed as a whole, so we propose a plate for a plate heat exchanger.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a plate heat exchanger plate, comprising a plate body, a splicing rod is installed at the rear end of the plate body, a pop-up outlet is opened at the top of the splicing rod, a pressing groove is opened inside the pop-up outlet, an elastic spring is fixedly connected inside the pressing groove, a pressing block is fixedly connected to the top of the elastic spring, a connecting block is installed at the front end of the plate body, a slot is opened inside the connecting block, and a limiting groove is opened at the top of the slot.

[0007] Preferably, sliding grooves are provided on both sides of the pressing groove, sliding blocks are fixed on both sides of the pressing block, and the interior of the sliding groove is slidably connected to the sliding blocks.

[0008] Preferably, the surface of the pressing block is provided with an inclined surface.

[0009] Preferably, the size of the pressing block is matched with the limiting groove.

[0010] Preferably, a rubber sleeve is installed inside the connecting block.

[0011] Preferably, a reinforcement block is fixedly connected to the bottom end of the connecting block.

[0012] Preferably, the main body material of the plate body is ceramic.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, when the staff needs to splice the plate body, the pressing block is pressed inward to allow the elastic spring to store force. At this time, the splicing rod is inserted into the slot. When the pressing block is aligned with the limiting slot, the elastic force stored in the elastic spring is released to drive the pressing block to pop out quickly into the limiting slot, so that the plate bodies can be quickly spliced. The spliced ​​plate bodies can be adjusted individually to increase their flexibility and improve their use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 6When the plate body 1 is connected with the support 1, the support 1 is provided with a plurality of springs, and the springs 5 ​​are provided with a plurality of springs, and the plurality of springs 5 ​​are provided with a plurality of springs 6. When the plate body 1 is connected with the support 1, the plurality of springs 6 are provided with a plurality of springs 6 and a plurality of springs 6 are provided in the plurality of springs 6.

[0024] Reference Figure 5 As shown, in the present embodiment: sliding grooves 10 are provided on both sides of the pressing groove 4, and sliders 11 are fixed on both sides of the pressing block 6. The interior of the sliding groove 10 is slidably connected to the slider 11. Through the setting of the sliding groove 10 and the slider 11, the elastic spring 5 can form a stable limit in the process of driving the pressing block 6 to pop out, preventing it from falling off due to excessive popping out, which affects the normal fixation between the plate body 1.

[0025] Reference Figure 5 As shown, in this embodiment: a slope 12 is provided on the surface of the pressing block 6. Through the setting of the slope 12, when the plate main bodies 1 need to be separated, the two plate main bodies 1 are pulled to both sides. At this time, the slope 12 presses against the inside of the limiting groove 9 and moves therein due to the pulling force, so that the pressing block 6 retracts inward, and the pressing block 6 and the limiting groove 9 are released from the limit, thereby achieving rapid separation of the plate main bodies 1.

[0026] Reference Figure 5 and Figure 6 As shown, in this embodiment: the size of the pressing block 6 is adapted to the limiting groove 9. By configuring the pressing block 6 to be adapted to the limiting groove 9, the splicing between the plate main bodies 1 can be made more stable, thereby improving the splicing stability of the plate main bodies 1.

[0027] Reference Figure 6 As shown, in this embodiment: a rubber sleeve 13 is installed inside the connecting block 7. Through the setting of the rubber sleeve 13, the splicing rod 2 can form a tighter fitting effect when sliding into the rubber sleeve 13 to prevent shaking.

[0028] Reference Figure 6As shown, in this embodiment: the bottom end of the connecting block 7 is fixedly connected with a reinforcing block 14. Through the setting of the reinforcing block 14, the connecting block 7 can be fixed more firmly on the surface of the plate body 1 to prevent the connecting block 7 from falling off due to long-term use and affecting the splicing effect.

[0029] Reference Figure 1 As shown, in this embodiment: the main material of the plate body 1 is ceramic. Through the setting of this material, the plate body 1 can have better thermal conductivity and corrosion resistance and high temperature resistance, thereby improving the service life of the plate body 1.

[0030] Working principle: when the staff needs to splice the plate body 1, the pressing block 6 is pressed inward to store force in the elastic spring 5. At this time, the splicing rod 2 is inserted into the slot 8. When the pressing block 6 is aligned with the limiting slot 9, the elastic force stored in the elastic spring 5 is released to drive the pressing block 6 to pop out quickly into the limiting slot 9, so that the plate bodies 1 can be quickly spliced. The spliced ​​plate bodies 1 can be adjusted individually to increase their flexibility and improve their use effect. Through the setting of the slide groove 10 and the slider 11, the elastic spring 5 can form a stable limit in the process of driving the pressing block 6 to pop out, preventing it from falling off due to excessive popping out, affecting the normal fixation between the plate bodies 1. Through the setting of the inclined surface 12, when the plate bodies 1 need to be separated, the two plate bodies 1 are pulled to both sides. At this time, the inclined surface 12 presses against The plate body 1 is fastened to the plate body 1 by the rubber sleeve 13, and the splicing rod 2 can form a tighter fit when sliding into the rubber sleeve 13 to prevent shaking. The reinforcement block 14 can be set to make the connection block 7 more firmly fixed on the surface of the plate body 1 to prevent the connection block 7 from falling off due to long-term use and affecting the splicing effect. The material setting can make the plate body 1 have better thermal conductivity, corrosion resistance and high temperature resistance, and improve the service life of the plate body 1.
