[0023] Reference Figs. 1 to 4The embodiment of the present application provides a hot working plant temperature control system, which is used for cooperating with a distribution box of a hot working plant to control the environmental temperature in the plant, wherein a toughening furnace or multiple toughening furnaces, including an automatic toughening furnace and a manual toughening furnace, are arranged in the hot working plant and are used for toughening and hardening a glass cover plate. The hot working plant temperature control system comprises a summer fan M1 and a winter fan M2. The summer fan M1 and the winter fan M2 can be one or multiple, and can be specifically set according to different situations of the hot working plant. A furnace cover closing limit switch SQ is installed on a furnace cover of the toughening furnace, and the furnace cover closing limit switch SQ is electrically connected with the distribution box 10, so that the furnace cover closing limit switch SQ is identified to the furnace cover closing of the toughening furnace as a prerequisite for starting the summer fan M1 and the winter fan M2. The quality of the toughened glass can be prevented from being affected by sudden changes of environmental dust when the toughened glass is discharged from the furnace, and the glass can be prevented from being broken due to changes of environmental temperature difference. The operation of the fan (including the summer fan M1 and the winter fan M2) is stopped when any one of the toughening furnaces is opened.
[0024] The distribution box 10 is provided with a first switch group, a second switch group and a temperature controller T1, and the temperature controller T1 is provided with a temperature control switch W1. The first switch group and the temperature controller T1 are electrically connected with the summer fan M1. After the furnace cover is closed, when the environmental temperature of the hot working plant exceeds the set temperature of the temperature controller T1 in summer, for example, exceeds 27 degrees, the first switch group and the temperature control switch W1 are attracted, the summer fan M1 is started, and air is blown out of the hot working plant, so that the high temperature in the hot working plant is quickly transported to the area outside the hot working plant.
[0025] The second switch group and the temperature controller T1 are electrically connected with the winter fan M2. After the furnace cover is closed, when the environmental temperature of the hot working plant exceeds the set temperature of the temperature controller T1 in winter, the second switch group and the temperature control switch W1 are attracted, the winter fan M2 is started, and air is blown into the hot working plant, so that the environmental temperature of the area outside the hot working plant is transported into the hot working plant, and the purpose of quickly cooling the hot working plant by using the natural wind in winter is achieved.
[0026] Therefore, the hot working plant temperature control system can adaptively adjust the cooling strategy according to different seasons. In summer, the summer fan M1 is used to blow air out of the hot working plant to dissipate heat, and in winter, the winter fan M2 is used to blow air into the hot working plant to cool down, so that the temperature of the hot working plant can be regulated while the cost is reduced. In addition, the natural wind is used for cooling, so that the problem of glass cover plate being easily broken due to too large temperature difference caused by too low air outlet temperature of a conventional air conditioner can be avoided.
[0027] In one embodiment, the first switch group comprises a first relay KA1 and a first contactor KM1, wherein in summer, the first relay KA1 is attracted, wherein when the ambient temperature of the hot working shop exceeds the set temperature of the temperature controller T1, the temperature control switch W1 is closed, and the first contactor KM1 is attracted. In the case of the closing of the furnace cover of the toughening furnace, both the first relay KA1 and the first contactor KM1 need to be attracted, and the summer fan M1 will start, otherwise, the summer fan M1 will not start.
[0028] In one embodiment, the second switch group comprises a second relay KA2 and a second contactor KM2, wherein in winter, the second relay KA2 is attracted, wherein when the ambient temperature of the hot working shop exceeds the set temperature of the temperature controller T1, the temperature control switch W1 is closed, and the second contactor KM2 is attracted. Correspondingly, in the case of the closing of the furnace cover of the toughening furnace, both the second relay KA2 and the second contactor KM2 need to be attracted, and the winter fan M2 will start, otherwise, the winter fan M2 will not start.
[0029] In one embodiment, the distribution box 10 is connected to the summer fan M1 and the winter fan M2 through the speed regulator (speed regulator 1 and speed regulator 2), so that the speed of the fan can be flexibly adjusted through the speed regulator, for example, when the cooling speed is slow, the speed of the fan is increased, so that emergency cooling treatment can be carried out to ensure the ambient temperature of the furnace.
[0030] In one embodiment, the distribution box 10 is further provided with a summer stop switch SB1 and a winter stop switch SB2, wherein the furnace cover closing limit switch SQ is connected to the first relay KA1 through the summer stop switch SB1 to form a closed loop, and is connected to the second relay KA2 through the winter stop switch SB2 to form a closed loop, so that the reliability of the summer fan M1 and the winter fan M2 can be ensured by additionally providing the summer stop switch SB1 and the winter stop switch SB2, specifically, when in summer, the summer stop switch SB1 is closed in the case of the closing of the furnace cover, the first relay KA1 is attracted, at this time, it can be ensured that the winter stop switch SB2 is in the open state, so as to avoid the simultaneous operation of the summer fan M1 and the winter fan M2, and in winter, the situation is similar, in addition, the summer stop switch SB1 and the winter stop switch SB2 can be manual switches or electric control switches.
[0031] In one embodiment, the winter fan M2 is provided with a filter screen at the air inlet, so that the dust in the air inlet can be filtered when air is supplied to the hot working shop to ensure the environment in the hot working shop.
[0032] In one embodiment, the distribution box 10 is also installed with a temperature monitor T2, which is connected with an alarm horn BL, when the temperature exceeds a preset value, such as 50 degrees, the alarm horn BL is started, reminding the staff to check whether there is a fault, or the fan speed is too low, etc., to facilitate timely manual adjustment to quickly cool down, at the same time, the alarm horn BL is provided with a manual reset button, which must be manually reset to ensure safe operation.
[0033] It should be noted that the terms "first", "second" in the present application are only used for descriptive purposes, and do not indicate any order, and cannot be understood as indicating or implying relative importance, and these terms can be interpreted as names.
