[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0025] Please refer to Figs. 1-3As shown, the old sand water conditioning device comprises a belt conveyor 5, a plow-type mixer 6 fixedly connected above the belt conveyor 5, spray heads 7 arranged on the front and back sides of the plow-type mixer 6 along the material conveying direction, and liquid supply pipes 8 connected with the spray heads 7. The liquid inlet end of the liquid supply pipe 8 is provided with an electromagnetic flow valve 4, and the discharge end of the belt conveyor 5 is fixedly connected with a temperature sensor 1. The temperature sensor 1 and the electromagnetic flow valve 4 are electrically connected with a controller 14, which is used to control the opening degree of the electromagnetic flow valve 4 according to the material temperature detected by the temperature sensor 1.
[0026] When the material is conveyed by the belt conveyor 5, water is sprayed on the material by the spray heads 7 to cool the material. When the material passes through the plow-type mixer 6, the material is turned over under the action of the plow-type mixer 6, and then the material is sprayed with water again by the spray heads 7 to ensure the cooling effect, make the moisture more uniform, reduce dust, and make the bentonite in the old sand fully absorb water to improve the forming quality and yield of the subsequent processed products.
[0027] In this process, the discharge temperature is detected by the temperature sensor 1 and converted into an electrical signal to send to the controller 14. The controller 14 compares the actual temperature value with the preset temperature range and outputs a corresponding control signal to the electromagnetic flow valve 4. The electromagnetic flow valve 4 adjusts the position of the valve core according to the received control signal to change the flow of the medium, so that the discharge temperature is within the preset range. Specifically, the temperature sensor 1 is an infrared temperature sensor, and the controller 14 is a temperature controller.
[0028] In addition, the liquid inlet end of the liquid supply pipe 8 is provided with a water valve 3, which is closed when the equipment is idle.
[0029] In some embodiments, the plow-type mixer 6 has a plurality of plow-type mixers 6 arranged at intervals along the material conveying direction. By arranging multiple plow-type mixers 6, the material can be turned over multiple times to further improve the cooling effect. Preferably, the multiple plow-type mixers 6 are arranged at different positions along the material conveying direction. By arranging the plow-type mixers 6 at different positions, the turning over and mixing effect is improved.
[0030] In some embodiments, the plow-type mixer 6 comprises a framework 11, both sides of the framework 11 are fixedly connected with arc-shaped plates 12, and one end of the two arc-shaped plates 12 is fixedly connected. Preferably, the outer side of the bottom end of the arc-shaped plate 12 is provided with a wear-resistant layer 13. By arranging the wear-resistant layer 13, the wear of the plow-type mixer 6 can be slowed down, and the service life thereof can be improved.
[0031] In order to make the temperature detection of the temperature sensor 1 more accurate, the discharge end of the belt conveyor 5 is provided with a smoothing piece 2 for smoothing the material. By smoothing the material with the smoothing piece 2, the accuracy of temperature detection is ensured.
[0032] In order to avoid material from the belt conveyor 5 from the belt conveyor 5 both sides of the belt conveyor 5 are provided with a baffle 9.
