"It can be seen from this that the device belongs to the cooling of the molding sand during the circulation process. The molding sand enters the equipment from the sand inlet and then flows through the sand slide plate and then flows out from the sand outlet. The residence time of the molding sand in the old sand flow cooling and dust removal device is relatively short. The temperature inside the tower exceeds 200°C, the energy conversion utilization rate is low, and a large amount of cooling water is needed in the cooling process, the cooling effect is not obvious and the energy...

Embodiment 1）

[0049] See figure 1 , figure 2 and Figure 5 , The sand cooling device of this embodiment includes a vertical box 1, a feed port 2, a discharge port 3, an air inlet 4, a flow guiding device 5 and an air outlet 6.

[0050] See figure 1 , figure 2 and Figure 5 , the feed inlet 2 is airtightly and fixedly connected to the upper left side of the vertical box body 1 from the upper left, and communicates with the inside of the vertical box body 1 . The feed port 2 is provided with a corresponding valve which can control the feed port 2 to be in an open state or a closed state. The discharge port 3 is airtightly and fixedly connected to the lower end of the vertical box body 1 from below, and communicates with the inside of the vertical box body 1 . The discharge port 3 is provided with a corresponding valve, and the molding sand in the vertical box body 1 can be released by opening the valve. The lower part of the box body plate of the vertical box body 1 is provided with ...

Embodiment 2）

[0062] See Figure 7 , the rest of this embodiment is the same as Embodiment 1, the difference is: the lower air outlet 51-1-1 of the air inlet plate 51-1 of the flow guiding device 5, the communication air port 51-2-2 of the communication plate 51-2 1 and the upper air outlet 51-3-1 of the air outlet plate 51-3 are all provided with installation grooves 53 on the side close to the axis of the vertical box body, and the cross-sectional shape of each installation groove 53 is consistent with the bottom of the air inlet plate 51-1. The cross-sectional shape of the air outlet 51-1-1 is corresponding. Each installation groove 53 is airtightly and fixedly connected with the contacting part of the corresponding air inlet plate 51-1, communication plate 51-2 or air outlet plate 51-3, and the opening is downward. Each guide groove 52 - 1 is fixedly arranged on the corresponding two installation grooves 53 overlapping from top to bottom.

Embodiment 3）

[0064] See Figure 8 , the rest of this embodiment is the same as that of Embodiment 1, and the difference is that the cross-sectional shape of each flow guide groove 52-1 of the air outlet flow guide groove group 52 of the flow guide device 5 is the same as that of the air inlet plate 51-1. The rectangular cross-section of the gas port 51-1-1 corresponds to a rectangular shape. Each diversion groove 52-1 of the air outlet diversion groove group 52 of the diversion device 5 is provided with two protective plates 52-1-1. The two protective plates 52-1-1 are arranged on the diversion The junction of the groove walls on the front and rear sides of the groove 52-1 and the groove bottom on the upper side.

Abstract

The invention discloses a sand cooling apparatus. The sand cooling apparatus comprises a vertical casing, a material inlet and a material outlet. The apparatus also comprises a gas inlet, a guiding device and a gas outlet. The lower portion of the casing plate of the vertical casing is provided with gas inlet holes. The gas inlet is arranged outside the lower portion of the vertical casing, completely covers the gas inlet holes, and has a closed connection with the outer wall of the vertical casing. The upper right portion of the gas outlet is fixedly connected to the right side of the upper portion of the vertical casing in a closed manner, and is connected with the internal of the vertical casing. The guiding device is arranged in the vertical casing, the guiding device, the vertical casing and molding sand in the vertical casing form an S-shaped gas channel, and the gas channel connects the gas inlet with the gas outlet.

Description

technical field [0001] The invention relates to casting molding sand processing equipment, in particular to a sand cooling device for cooling molding sand. Background technique [0002] Sand casting is a commonly used part production method in the current metal product manufacturing industry. Sand casting is a process of molding with sand and then casting. After casting, most of the molding sand will be very hot, and these used molding sands are called used sand in the foundry industry. The continuous use of old sand in casting will affect the quality of castings, causing defects such as sand inclusions, sand sticking on the surface, sand washing, and pores. In addition, the old sand grit will stick to the mold and affect the geometry of the casting. In order to reduce production costs, the old sand is generally regenerated and reused through the sand treatment system, and the temperature of the old sand will directly affect the performance of the old sand. First of all,...
