Description

Technical Field

[0001] The utility model relates to the field of coating machine heating, and particularly relates to a steam heating device for a coating machine. Background Art

[0002] The coating machine is used for spraying slurry on the battery electrode plate and heating the slurry on the battery electrode plate during coating. The existing coating machine controls the input amount of steam through the valve opening to control the heating temperature. For example, the patent document with the Chinese application number 202020277806.6 and the publication date of October 30, 2020 discloses a temperature control structure for the tail section of a coating machine oven. A temperature control valve group for controlling the steam flow is arranged on the steam inlet pipeline of the heat exchanger in the tail section of the oven, and a steam pressure regulating valve group for adjusting the steam pressure is arranged in front of the temperature control valve group. A bypass air inlet pipe is added to the side of the return air duct of the tail section of the oven. The outer end of the bypass air inlet pipe is a fresh air inlet, and a filter is arranged at the fresh air inlet. A wind valve is arranged at the bypass air inlet pipe. This temperature control structure controls the steam flow through a temperature regulating positioning valve to control the temperature in the oven.

[0003] For battery electrode plates of different specifications, the thickness and size of the required slurry are different. For slurries coated with different specifications, different temperatures are required for drying. This temperature control structure only sets a group of steam heat sources, and the maximum and minimum temperatures of the steam heat sources are limited by the efficacy. When using a high-efficacy steam heat source to heat the slurry coated with a small specification, even if the steam heat source outputs the minimum temperature, the internal temperature of the coating machine is still too high, and thus the required temperature cannot be reached. When using a low-efficacy steam heat source to heat the slurry coated with a large specification, even if the steam heat source outputs the maximum temperature, the internal temperature of the coating machine is still too low, and thus the required temperature cannot be reached. Only setting a group of steam heat sources has a small temperature adjustment range and is not suitable for heating slurries of different specifications. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a steam heating device for a coating machine. The first fin group and the second fin group are used for heat exchange separately or jointly, and the first fin group and the second fin group can be used in combination or independently, and can output corresponding heat exchange efficacy according to the specification of the material, and the heating accuracy is good.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A steam heating device for a coating machine according to the utility model includes a heat exchanger. The heat exchanger is provided with a first fin group and a second fin group. The first fin group and the second fin group are respectively connected to a heat source. The heat exchange efficacy of the first fin group is greater than that of the second fin group. The first fin group and the second fin group are used for heat exchange separately or jointly.

[0007] Preferably, the heat exchange area of the first fin group is larger than that of the second fin group.

[0008] Preferably, the first fin group includes more than two first fins, the second fin group includes more than two second fins, and the area of the first fin is larger than that of the second fin.

[0009] Preferably, the first fin group includes more than two first fins, the second fin group includes more than two second fins, and the number of the first fins is larger than that of the second fins.

[0010] Preferably, the heat exchanger is further connected with a first intake pipe, a first outlet pipe, a second intake pipe and a second outlet pipe; one end of the first intake pipe is connected to a heat source, the other end of the first intake pipe is connected to the input end of the first fin group, and a first stop valve is arranged in the first intake pipe; the first outlet pipe is connected to the output end of the first fin group.

[0011] One end of the second intake pipe is connected to a heat source, the other end of the second intake pipe is connected to the input end of the second fin group, and a second stop valve is arranged in the second intake pipe; the second outlet pipe is connected to the output end of the second fin group.

[0013] Preferably, a first check valve is arranged in the first outlet pipe; a second check valve is arranged in the second outlet pipe.

[0014] The beneficial effects of the steam heating device for a coating machine according to the present utility model compared with the prior art are mainly reflected in:

[0015] The heat exchange effects of the first fin group and the second fin group are different, and the first fin group and the second fin group can be combined or used independently. In this way, the first fin group can be used alone to heat the slurry for one specification of coating, the second fin group can be used alone to heat the slurry for another specification of coating, and the first fin group and the second fin group can be used simultaneously to heat the slurry for yet another specification of coating; the corresponding effects can be output according to the specifications of the materials, so that when heating materials of different specifications, the internal temperature of the coating machine can reach the required temperature; the situations of too high and too low internal temperature of the coating machine are avoided, and the heating accuracy is good.

[0016] By changing the heat exchange area to change the heat exchange effect, at the same time, the overall heat exchange area can be increased by increasing the area of each fin or by increasing the number of fins; the structure is simple.

[0017] The first fin group and the second fin group are independently arranged. The first intake pipe is set to convey heat source to the first fin group, and the first outlet pipe outputs the condensed water generated during the heat exchange process of the first fin group; the second intake pipe is set to convey heat source to the second fin group, and the second outlet pipe outputs the condensed water generated during the heat exchange process of the second fin group; the first intake pipe and the second intake pipe, the first outlet pipe and the second outlet pipe are all independently arranged. When used independently, there will be no mutual interference between the first fin group and the second fin group; when used together, the first fin group and the second fin group can also cooperate with each other.

[0018] When using the first fin group alone for heat exchange, open the first stop valve and close the second stop valve, and the heat source is input into the first fin group; when using the second fin group alone for heat exchange, open the second stop valve and close the first stop valve, and the heat source is input into the second fin group; when using the first fin group and the second fin group together for heat exchange, open the first stop valve and the second stop valve, and the heat source is input into the first fin group and the second fin group, and the heat exchange area of the first fin group is superimposed on the heat exchange area of the second fin group to increase the heat exchange area acting on the material and improve the heat exchange efficiency acting on the material.

[0019] A regulating valve is set. By adjusting the opening degree of the regulating valve, the input amount of the heat source is changed, and thus a suitable temperature can be selected between the maximum temperature and the minimum temperature of the current heat exchange efficiency; it is convenient to use; through the first check valve and the second check valve, the condensed water in the first outlet pipe and the condensed water in the second outlet pipe are prevented from flowing back into the heat exchanger to affect heating.

[0020] In the present utility model, the first fin group and the second fin group are used for heat exchange alone or together, and the first fin group and the second fin group can be used in combination or independently, and corresponding effects can be output according to the specifications of the material, and the heating accuracy is good.
