Sand mixing machine for casting

Abstract

The invention provides a sand mixing machine for casting. The sand mixing machine comprises a work table, an inner cavity, a sand mixing box, an old sand cabin and a new sand cabin, wherein the sand mixing box is arranged at the upper end surface of the work table; the old sand cabin is arranged at the right side of the upper end surface of the sand mixing box; the new sand cabin is arranged at the left side of the upper end surface of the sand mixing box; an inner cavity is formed in the bottom position of the sand mixing box; a rotating motor is assembled in the middle position inside the inner cavity; a stirring blade is arranged inside the sand mixing box; a water storage box is assembled right under the work table; the left end surface of the water storage box is connected with a first water outlet pipe; a water pumping pump is arranged at the left end surface of the first water outlet pipe; a second water outlet pipe is arranged at the inner wall of the sand mixing box; a plurality of groups of high-pressure spray heads are assembled on the outer surface of the second water outlet pipe; the first water outlet pipe is connected with the second water outlet pipe. Through the design, the residues on the outer surface of the stirring blade can be conveniently cleaned in time; the influence on the stirring efficiency caused by the residue attached onto the stirring blade can be prevented. The structure is reasonable; the installation is convenient; the reliability is high.

Description

technical field [0001] The invention relates to a sand mixer for casting, which belongs to the technical field of casting equipment. Background technique [0002] The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. Sand mixer is a kind of sand processing equipment widely used in foundry industry. [0003] In the prior art, the existing foundry sand mixer does not have a cleaning structure. After the new sand and the old sand are mixed and stirred inside the sand mixer, a large amount of residue remains on the stirring blade and needs to be cleaned in time to prevent the influence of a large amount of residue attached to the stirring blade.

Problems solved by technology

[0003] In the prior art, the existing foundry sand mixer does not have a cleaning structure. After the new sand and the old sand are mixed and stirred inside the sand mixer, a large amount of residue remains on the stirring blade and needs to be cleaned in time to prevent the influence of a large amount of residue attached to the stirring blade. Stirring and mixing efficiency, the existing casting sand mixer does not have no heat dissipation structure, and the motor needs to dissipate heat in time to prevent the motor from being in operation for a long time and affect the service life of the motor. Now there is an urgent need for a foundry sand mixer to solve the problem. The above problems
