[0014] As Figure 1As shown, the casting sand spraying agent mixing and spraying device comprises a mixing mechanism, a spraying mechanism and a spraying table 6, the mixing mechanism comprises a mixing barrel 1 and a liquid storage barrel 2, stirring structures are respectively arranged in the mixing barrel 1 and the liquid storage barrel 2, the mixing barrel 1 is located above the liquid storage barrel 2, the lower end of the mixing barrel 1 is connected to the liquid storage barrel 2 through a liquid discharge pipe provided with a valve 3, the spraying mechanism comprises a booster pump, a spraying pipe 4 and a plurality of nozzles 5, the booster pump is connected to the liquid storage barrel 2, the nozzles 5 are located above the spraying table 6 and are connected to the booster pump through the spraying pipe 4, and supports 13 for fixing the spraying pipe 4 are respectively arranged on the two sides of the spraying table 6. Water, a releasing agent and various additives are put into the mixing barrel 1 and are stirred by the stirring structure to be uniformly mixed. Then, the prepared spraying agent is stored in the liquid storage barrel 2. When spraying is needed, the sand is laid on the table top of the spraying table 6, and the spraying agent is sprayed on the surface of the sand by the nozzles 5 connected to the booster pump. The sand is continuously stirred so that the surface of the sand is uniformly covered with a layer of spraying agent. The mixing barrel 1 and the liquid storage barrel 2 can be used to store the prepared spraying agent at any time.

[0015] Further, the table top of the spraying table 6 is gradually inclined from front to back, and the surrounding plates 7 are fixedly connected to the two sides and the back of the spraying table 6. The table top of the spraying table 6 is inclined, the sand on the table top can be stirred, and the water content of the sand can be controlled. The specific process of controlling the water content is as follows: if the water content of the sand is too high, the sand is stirred to the high part of the table top, and the water content of the sand at the high part is quickly controlled by the self-weight of the water. If the water content of the sand is too low, in addition to spraying new spraying agent by the nozzles 5, the sand can also be stirred to the low part of the table top, and the water content is controlled by mixing with the sand with high water content at the low part. The sand with the water content meeting the requirements is discharged from the high part of the table top of the spraying table 6. In order to facilitate the discharge of the sand, the front of the spraying table 6 is provided with an extension space for the extension of a sand transfer cart.

The distance between the nozzles 5 and the highest point of the table top of the spraying table 6 is equivalent to the distance between the nozzles 5 and the lowest point of the table top of the spraying table 6, so that the sand laid on the table top of the spraying table 6 can be uniformly sprayed by the nozzles 5.

[0018] Further, the mixing barrel 1 and the liquid storage barrel 2 are respectively arranged on the mounting frame 10, the stirring structure comprises a stirring motor 11 and a stirring shaft 12, the stirring shaft 12 extends into the mixing barrel 1 or the liquid storage barrel 2 and is connected with stirring blades. The mixing barrel 1 is stirred by the stirring structure during the material mixing process, so that the materials are uniformly mixed. The spraying agent in the liquid storage barrel 2 is stirred by the stirring structure at a regular time, so that the precipitation is prevented.

[0019] Further, the liquid storage barrel 2 is provided with an infrared liquid level meter. The liquid level in the liquid storage barrel 2 can be real-timely reflected by the infrared liquid level meter, so that the new spraying agent can be timely supplemented.

[0020] It is worth mentioning that the technical features such as the booster pump involved in the utility model patent application should be regarded as the prior art, the specific structure, working principle and possible control mode and spatial arrangement mode of these technical features can be selected by using the conventional selection in the field, and should not be regarded as the invention point of the utility model patent, and the utility model patent will not be further expanded and described in detail.
