[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-Figure 3 As shown, a box-type wide-channel flat plate heat exchanger includes a base plate 1, the top of the base plate 1 is fixedly connected to four supporting legs 11 in a rectangular array, the top of the supporting legs 11 is fixedly connected to a heat exchange mechanism 2, the left part of the top of the base plate 1 is fixedly connected to a cooling mechanism 3, the heat exchange mechanism 2 includes a box body 21, the bottom end of the box body 21 is fixedly connected to the top of the supporting legs 11, the cooling mechanism 3 includes a cooling water tank 31, the bottom end of the cooling water tank 31 is fixedly connected to the left part of the top of the base plate 1.

[0024] The heat exchange mechanism 2 and the cooling mechanism 3 cooperate with each other to exchange heat between the material and the coolant, thereby completing the cooling of the material.

[0025] like Figure 2 , Figure 3 As shown, the inner cavity of the box body 21 is fixedly connected with a partition 22 in a linear array, the front and rear ends of the partition 22 are fixedly connected with a flat plate heat exchanger 4, the top of the left end of the box body 21 is fixedly connected with a feed port 23, and the bottom of the left end of the box body 21 is fixedly connected with a discharge port 24.

[0026] The material is transported from the feed port 23 into the box body 21, so that the material flows on the partition 22. At the same time, the cavity formed between the partitions 22 is straight and wide, which greatly increases the flow of the material and speeds up the work efficiency.

[0027] like Figure 2-Figure 5 As shown, the left and right ends of the box body 21 are plugged with distribution pipes 25 , and the upper and lower ends of the distribution pipe 25 are fixedly connected with elastic sealing strips 26 , and the outer wall of the elastic sealing strip 26 is plugged with the inner wall of the box body 21 .

[0028] When the outer wall of the distribution tube 25 is plugged into the inner wall of the box body 21, the elastic sealing strip 26 is driven to move synchronously, so that the outer wall of the elastic sealing strip 26 is slidably connected with the inner wall of the box body 21. When the outer wall of the elastic sealing strip 26 is plugged into the inner wall of the box body 21, the pushing of the distribution tube 25 can be stopped.

[0029] like Figure 3 , Figure 5 As shown, the front and rear ends of the material distribution pipe 25 are fixedly connected with a fixing plate 27, one end of the fixing plate 27 is fixedly connected with a positioning block 28, the outer wall of the positioning block 28 is plugged into the inner wall of the box body 21, the upper and lower parts of the fixing plate 27 are threadedly connected with bolts 29, and the outer wall of the bolts 29 is threadedly connected to the inner wall of the box body 21.

[0030] By unscrewing the bolt 29, the outer wall of the bolt 29 is no longer in contact with the inner wall of the box body 21. Then, the distribution tube 25 can be pulled, so that the distribution tube 25 drives the elastic sealing strip 26 to slide on the inner wall of the box body 21, so that the outer wall of the elastic sealing strip 26 is no longer plugged into the inner wall of the box body 21. In this way, the distribution tube 25 can be taken out and cleaned, which makes it easy to disassemble and clean.

[0031] like Figure 2 As shown, a water inlet pipe 32 is fixedly connected to the left portion of the top of the cooling water tank 31, a filter screen 33 is fixedly connected to the top of the inner cavity of the cooling water tank 31, a water pump 34 is fixedly connected to the left portion of the top of the cooling water tank 31, and the output and input ends of the water pump 34 are fixedly connected to connecting pipes 35, the outer wall of the connecting pipe 35 at the input end is fixedly connected to the inner wall of the filter screen 33, and the rear end of the connecting pipe 35 at the output end is fixedly connected to a water inlet 36, the outer wall of the water inlet 36 passes through the outer wall of the box body 21 and is fixedly connected to a cooling pipe 37, the rear end of the cooling pipe 37 is fixedly connected to the outer wall of the flat plate heat exchanger 4, the top of the cooling pipe 37 is fixedly connected to a water outlet pipe 38, the outer wall of the water outlet pipe 38 is fixedly connected to the inner wall of the box body 21, and the connecting pipe 35, the water inlet 36, the cooling pipe 37 and the water outlet pipe 38 are interconnected.

[0032] By starting the water pump 34, the coolant in the cooling water tank 31 is extracted through the connecting pipe 35 and transported to the water inlet 36. The coolant is transported to the cooling pipe 37 through the water inlet 36, so that the coolant circulates in the cooling pipe 37 from bottom to top. In this process, the coolant and the material are subjected to heat exchange under the action of the flat plate heat exchanger 4, thereby completing the cooling of the material. The coolant in the cooling pipe 37 is finally discharged from the water outlet pipe 38. When the coolant in the cooling water tank 31 is used up, coolant is added to the cooling water tank 31 through the water inlet pipe 32, and the coolant is filtered by the filter screen 33 to filter out impurities in the coolant to prevent subsequent cooling pipe 37 from being blocked, thereby achieving the effect of preventing blockage.

[0033] The working principle of the utility model is as follows: when in use, the material is transported from the feed port 23 to the box body 21, so that the material circulates on the partition 22. When the material circulates to the distribution pipe 25, the distribution pipe 25 distributes and guides the material so that the material falls on the partition 22 of the next layer, and the material is circulated in sequence, so that the material is finally discharged from the discharge port 24. During this process, the water pump 34 is started, and the coolant in the cooling water tank 31 is extracted by the connecting pipe 35 and transported to the water inlet 36. The coolant is transported to the cooling pipe 37 from the water inlet 36, so that the coolant circulates in the cooling pipe 37 from bottom to top. During this process, the coolant and the material are exchanged with each other under the action of the flat plate heat exchanger 4, thereby completing the cooling of the material. The coolant in the cooling pipe 37 is finally It is discharged from the water outlet pipe 38. When the coolant in the cooling water tank 31 is used up, coolant is added to the cooling water tank 31 through the water inlet pipe 32. The coolant is filtered by the filter screen 33 to filter out impurities in the coolant to prevent the subsequent cooling pipe 37 from being blocked, thereby preventing blockage. Subsequently, if the corner of the distribution pipe 25 is blocked, the bolt 29 is unscrewed so that the outer wall of the bolt 29 no longer contacts the inner wall of the box body 21. After that, the distribution pipe 25 can be pulled so that the distribution pipe 25 drives the elastic sealing strip 26 to slide on the inner wall of the box body 21, so that the outer wall of the elastic sealing strip 26 is no longer plugged into the inner wall of the box body 21. In this way, the distribution pipe 25 can be taken out and cleaned, which makes it easy to disassemble and clean, thereby greatly improving the user experience.
