Description

Technical Field

[0001] The utility model relates to dyeing and finishing equipment, in particular to a drying room temperature regulating device. Background Art

[0002] Nowadays, some high-end printing and dyeing factories process small batches of high-quality fabrics in lean production. They produce as much as the order quantity requires. Often, several types of fabrics need to be changed in one shift. Since process parameters such as drying room temperature and width need to be adjusted every time the fabric is changed, the adjustment efficiency of the drying room temperature is crucial for production efficiency.

[0003] Currently, the method for cooling the drying room is to open the door and blow air to cool it, which has problems such as energy consumption waste, troublesome operation, and long occupation time. The utility model patent with Chinese patent number 202321819793.0 discloses a rapid cooling mechanism for an oven. Through the settings of a fresh air pipe, a first controllable valve, a second controllable valve, and a third controllable valve, when the oven needs to be rapidly cooled after shutdown, the steam heater stops steam heating, the exhaust device does not stop, the second controllable valve and the third controllable valve are closed, the first controllable valve is opened, and the fresh air does not directly pass through the steam heater but directly enters the oven at a lower temperature and is ejected from the air nozzles to rapidly reduce the temperature inside the oven and reduce the cooling time. However, this structure requires opening many air duct valve structures in the drying room, and has the defects of complex structure and large transformation difficulty. Therefore, it is necessary to develop a drying room cooling device with a simple structure and easy to transform. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drying room temperature regulating device.

[0005] The technical solution for achieving the purpose of the present utility model is: a drying room temperature adjustment device, which includes a first intake pipe, a radiator, a first outlet pipe, and a gas storage tank; the radiator is located inside the drying room, the first intake pipe extends into the drying room from outside the drying room, the first intake pipe has an intake front end and an intake rear end, the intake front end is connected to a steam generating device, an intake pipe control valve group is installed on the intake front end, the intake rear end is connected to the radiator, the first outlet pipe has an outlet front end and an outlet rear end, the radiator has a heat dissipation outlet end, the heat dissipation outlet end is connected to the outlet front end through an outlet branch pipe, and an outlet water pipe control valve group is installed on the outlet rear end; the gas storage tank is located outside the drying room, a pressure relief valve and a temperature control module for detecting the temperature inside the tank are installed on the gas storage tank, a water outlet pipe is installed at the bottom of the gas storage tank, and a steam trap is installed on the water outlet pipe; the bottom of the gas storage tank is connected to the first outlet pipe through an intake branch pipe, and an inlet electric valve and an air pump are sequentially installed on the intake branch pipe from bottom to top; a steam mixing pipe is installed on the first intake pipe behind the intake pipe control valve group, the steam mixing pipe has a first intake port, a second intake port, and an outlet port, the first intake port and the outlet port are respectively connected to the first intake pipe, the top of the gas storage tank is connected to the second intake port through a second outlet pipe, and an outlet electric valve is installed on the second outlet pipe.

[0006] Further, the steam mixing pipe is a Venturi tube. This prevents the steam from the high-temperature and high-pressure steam source in the first intake pipe from flowing back into the gas storage tank.

[0007] Further, several partition plates are sequentially and staggeredly installed on the inner wall of the gas storage tank from bottom to top. The staggeredly arranged partition plates construct a meandering upward serpentine air flow channel inside the gas storage tank, which can ensure the orderly flow of the steam in the tank from the inlet to the outlet and prevent air from mixing.

[0008] The drying room temperature adjustment device realized by the present utility model sends high-temperature and high-pressure steam into the radiator through the first intake pipe to achieve rapid heating inside the drying room. There is low-temperature steam stored in the radiator. When the drying room needs to be cooled down, the high-temperature steam in the radiator is introduced into the gas storage tank, and then the low-temperature steam in the gas storage tank is squeezed into the first intake pipe and introduced into the radiator through the second intake pipe to achieve rapid cooling. Its structure is simple and easy to transform, improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The working principle of the drying room temperature regulating device implemented in this embodiment is as follows:

[0014] 1) Initial working state of the drying room temperature regulating device: the intake pipe control valve group 5 and the outlet pipe control valve group 6 are in the open state; the outlet electric valve 49 and the inlet electric valve 46 of the gas storage tank 4 are in the closed state; at this time, there is low-temperature steam and low-temperature liquid slowly liquefying inside the gas storage tank 4, and the steam trap 7 starts to work to discharge the low-temperature liquid;

[0015] 2) The drying chamber starts to cool down: The inlet pipe control valve group 5 and the outlet pipe control valve group 6 are in the closed state; the outlet electric valve 49 and the inlet electric valve 46 are in the open state; the air pump 47 is started, and the high-temperature steam in the radiator 2 is pumped into the gas storage tank 4 through the first outlet pipe 3. The original low-temperature steam in the gas storage tank 4 is squeezed into the radiator 2 in the oven 10 through the second outlet pipe 48 and the Venturi tube 8; the high-temperature steam in the radiator 2 is cooled through heat exchange into low-temperature steam, and the low-temperature steam in the gas storage tank 4 becomes high-temperature steam, achieving the purpose of cooling the drying chamber;

[0016] 3) The heat exchange in the drying chamber is completed: When the temperature control module 42 detects the high-temperature steam in the gas storage tank 4, it means that the gas storage tank 4 is full of high-temperature steam at this time and the heat exchange purpose is achieved. The temperature control module 42 controls the outlet electric valve 49, the air pump 47, and the inlet electric valve 46 to close; at this time, the inlet pipe control valve group 5 and the outlet pipe control valve group 6 are also in the closed state;

[0017] 4) The drying chamber starts to heat up: When the equipment starts to run and the drying chamber 10 starts to work normally, at this time, the inlet pipe control valve group, the outlet pipe control valve group 6, the outlet electric valve 49, the air pump 47, and the inlet electric valve 46 are opened; the high-temperature steam in the gas storage tank 4 is mixed with the high-temperature and high-pressure steam through the Venturi tube 8 until all the high-temperature steam in the gas storage tank 4 is output. At this time, the temperature control module 42 detects the low-temperature steam, which means that the high-temperature steam recovery process is completed. Then the temperature control module 45 controls the outlet electric valve 49, the air pump 47, and the inlet electric valve 46 to close, waiting to enter the next oven cooling and heat exchange process.

[0018] The steam mixing pipe of the present utility model is not limited to the Venturi tube. When using the Venturi tube, it can prevent the steam from the high-temperature and high-pressure steam source in the first inlet pipe from flowing back into the gas storage tank; the partition plate is set as needed. When the partition plate is added in the gas storage tank, the staggered partition plates can ensure the orderly flow of the steam in the tank from the inlet to the outlet and prevent gas mixing; the structures of the inlet pipe control valve group, the outlet pipe control valve group, the steam trap, the Venturi tube, the air pump, the inlet electric valve, the outlet electric valve, the temperature control module, and the pressure relief valve of the present utility model are all prior arts and will not be elaborated here.

[0019] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent process transformations made using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
