[0021] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0022] Please see Figures 1 to 3 The embodiment of the utility model provides a constant temperature curing kiln for permeable bricks, which is used for curing permeable bricks, including a plurality of curing chambers 1 arranged in parallel, and a temperature and humidity balancing device is respectively arranged on the top of each curing chamber 1, and the temperature and humidity balancing device includes a spray device 2 and a circulating fan 3, the spray device 2 is arranged on the top of the curing chamber 1, and is arranged at intervals along the length direction of the curing chamber 1, the spray device 2 sprays water mist downward from the top of the curing chamber 1, and the circulating fan 3 is a circulating fan or an axial flow fan, which is arranged on the top of the curing chamber 1 and close to one end of the curing chamber 1, and the circulating fan 3 is arranged horizontally, and the blowing port of the circulating fan 3 faces the other end of the curing chamber 1. During the spraying process, the spray device 2 is combined with the circulating fan 3, and the airflow blown by the circulating fan 3 is used to drive the water mist to mix and flow up and down in the curing chamber 1, so that the temperature and humidity above and below the curing chamber are evenly distributed.

[0023] Specifically, the spray device 2 includes a water pump 21, a water pipe 22 and a plurality of spray heads 23. The water pipe 22 is arranged at the top of the curing room 1 and extends along the length direction of the curing room 1. The plurality of spray heads 23 are arranged at intervals on the water pipe 22. The spray direction of the spray head 23 is downward. The input end of the water pipe 22 is connected to the external water supply pipe 8, and water is supplied through the water supply pipe 8. The water pump 21 is arranged at the input end of the water pipe 22, and is used to pressurize the water entering the water pipe 22 toward the spray head 23, so as to assist the spray head 23 in spraying in the curing room 1. During the curing process of the permeable bricks, the spray head 23 sprays water mist downward from the top of the curing room 1 to humidify the curing room 1, and at the same time, the circulating fan 3 is turned on to blow horizontally in the curing room 1 to disturb the airflow, so that the humid air in the curing room 1 mixes and flows up and down. The water mist sprayed by the spray device 2 will form a heat exchange with the heat above the curing room 1, and the water mist will drift downward under the action of the circulating fan 3 and its own gravity, so that the temperature and humidity above and below the curing room 1 are evenly distributed, which is conducive to ensuring the uniform quality of the same batch of permeable bricks. In addition, the circulating fan 3 blows horizontally, which can cause the water mist or moisture to form a horizontal drifting flow in the curing room, which is conducive to the contact between the water mist or moisture and each layer of permeable bricks being cured.

[0024] Please see Figure 3 to Figure 4 Furthermore, a humidifying water tank 4 is respectively provided at the bottom of each of the curing chambers 1. The humidifying water tank 4 is arranged along the length direction of the curing chamber 1. The humidifying water tank 4 is used to collect water sprayed by the spray head 23.

[0025] Furthermore, in order to prevent the water in the humidifying water tank 4 from overflowing and save water resources, a circulating water pipe 5 is arranged between the humidifying water tank 4 and the water supply pipe 22, the input end of the circulating water pipe 5 is connected to the output end of the humidifying water tank 4, the output end of the circulating water pipe 5 is connected to the input end of the water supply pipe 22 by setting a connecting tee, a valve is arranged on the circulating water pipe 5, and a filter screen 6 is arranged at the output end of the humidifying water tank 4, the water in the humidifying water tank 4 can enter the circulating water pipe 5 after being filtered through the filter screen 6, when there is too much water in the humidifying water tank 4, the water pump 21 can be used for suction, and the water collected in the humidifying water tank 4 can be delivered to the spray head 23 for circulating spraying.

[0026] Please continue to see Figure 3 to Figure 4Furthermore, by arranging a water evaporation device 7 in the humidifying water tank 4, the water evaporation device 7 is an electric heating rod. By using the electric heating rod to heat the water in the humidifying water tank 4, the evaporation of water can be accelerated to humidify the curing room 1. A hot air blower can also be arranged at the open part of the humidifying water tank 4, and the water in the humidifying water tank 4 can be blown with hot air by the hot air blower to accelerate the volatilization of water vapor, thereby effectively ensuring the humidity in the curing room 1.

[0027] Please see Figure 2 Furthermore, in order to avoid the temperature of the spray water being too low in winter, which would affect the maintenance of the permeable bricks, a water heating device 24 is provided at the input end of each water pipe 22. The water heating device 24 uses an electric heating tape, which is wound around the water pipe 22 and can heat the water in the water pipe 22.
