Description

Technical Field

[0001] The utility model relates to the field of hot blast stove heat exchangers, and more specifically, to a heat exchanger plate applied to a hot blast stove system. Background Art

[0002] Fuel hot blast stoves are currently widely used as heat sources in agricultural product baking houses such as tobacco leaves and vegetables. Its working principle is: it is transported to the hot blast stove furnace through a feeding device for combustion, and the hot air generated by the flame heats the air in the heat exchanger to generate hot air, and the hot air is transported to the baking house to provide heat for the baking work. The commonly used heat exchanger in the current hot blast stove is a plate heat exchanger. Although it can better achieve heat exchange and heat the air, when installing it, multiple plates need to be sequentially clamped between the positioning guide rods. Due to the lack of a fixing device for the plates, when strengthening the plates, the installer needs to manually fix the installed plates, so there are great inconveniences during installation.

[0016] Embodiment 1

[0017] As Figures 1-3 shown, this embodiment provides a heat exchanger plate applied to a hot blast stove system, which includes a plate body 110, a first shelf plate 120 and a second shelf plate 130 arranged at both ends of the plate body 110. Heat conduction grooves 190 are provided at the plate body 110. There are two positioning guide rods 140 between the first shelf plate 120 and the second shelf plate 130. The two positioning guide rods 140 are arranged oppositely along the height direction of the plate body 110. A plate groove 210 for clearance fit with the positioning guide rods 140 is provided at the plate body 110. A plurality of clamping grooves 310 arranged along the length direction of the positioning guide rods 140 are provided at the end faces of the two positioning guide rods 140 close to the plate body 110. Clamping blocks 220 matching with the clamping grooves 310 are provided at the plate groove 210 of the plate body 110.

[0018] When installing the heat exchanger of the hot blast stove, connect the two positioning guide rods 140 to the first frame plate 120, and then install the plate body 110 between the two positioning guide rods 140 in sequence from the first frame plate 120. Before installing the plate bodies 110, the plate body 110 can be fixed between the two positioning guide rods 140 through the cooperation between the clamping blocks on the plate body 110 and the card slots 310 of the positioning guide rods 140. Therefore, it is avoided that the plate body 110 topples or displaces after the plate body 110 is installed between the positioning guide rods 140, thus facilitating the installation of the plate body 110 by the workers.

[0019] In this embodiment, the first frame plate 120 is connected to the two positioning guide rods 140 by bolts 160. The second frame plate 130 is provided with a frame plate groove 150 for clearance fit with the two positioning guide rods 140, and the frame plate groove 150 is provided with a fixing mechanism for fixing the two positioning guide rods 140. The fixing mechanism includes an installation block 410 arranged at the frame plate groove 150. The installation block 410 is provided with a screw hole 420, and a bolt 160 for abutting against the two positioning guide rods 140 to fix the two positioning guide rods 140 is arranged at the screw hole 420.

[0020] In this embodiment, through the setting of the fixing mechanism, after the plate body 110 is installed, the second frame plate 130 can be pushed to abut against the plate body 110, and then the bolt 160 is tightened so that the end of the bolt 160 abuts against the positioning guide rod 140, thereby realizing the fixation of the plate body 110.

[0021] Combined Figure 4 As shown, both the first frame plate 120 and the second frame plate 130 are provided with frame plate through holes 430. The first frame plate 120 is provided with a bolt rod 170 for tightening the first frame plate 120 and the second frame plate 130 to clamp the plate body 110. The end of the bolt rod 170 passes through the frame plate through hole 430 at the second frame plate 130, and bolt rod nuts 180 are arranged at the ends of the two positioning guide rods 140 passing through the frame plate through hole 430 at the second frame plate 130.

[0022] After the plate body 110 is fixed by the second frame plate 130, the first frame plate 120 and the second frame plate 130 can be tightened by the bolt rod 170 and the bolt rod nuts 180, so as to further clamp the plate body 110, avoiding the loosening between multiple plate bodies 110 and resulting in heat loss, thereby further improving the stability of the heat exchanger during use.

[0023] The specific working principle of the heat exchanger plate applied to the hot blast stove system in this embodiment is as follows: When installing the heat exchanger of the hot blast stove, connect 2 positioning guide rods 140 to the first mounting plate 120, and then install the plate body 110 between the 2 positioning guide rods 140 in sequence from the first mounting plate 120. Before installing the plate bodies 110, fix the plate body 110 between the 2 positioning guide rods 140 through the cooperation between the clamping blocks on the plate body 110 and the card slots 310 of the positioning guide rods 140; then push the second mounting plate 130 to abut against the plate body 110, and then tighten the bolt 160 so that the end of the bolt 160 abuts against the positioning guide rod 140; afterwards, tighten the first mounting plate 120 and the second mounting plate 130 through the bolt rod 170 and the bolt rod nut 180, so as to further clamp the plate body 110.

[0024] In conclusion, the above are only the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the patent of the present invention.
